It’s possible to grow meat in a lab — to cultivate animal cells without an animal and turn them into something people can eat. However, that process is difficult and expensive. And at the moment, lab-grown meat isn’t commercially available and probably won’t be for a long time, if ever.

Still, if and when lab-grown meat, also sometimes referred to as cultured meat, makes it onto the market at less than outrageous prices, a significant number of people will probably buy it. Some will do so on ethical grounds, preferring not to have animals killed to grace their dinner plates. Others will do so in the belief that growing meat in labs does less damage to the environment than devoting acres and acres to animal grazing. And it’s at least possible that lab-grown meat will eventually be cheaper than meat from animals.

And if some people choose to consume lab-grown meat, why not? It’s a free country, right?

Not if the likes of Ron DeSantis have their way. Recently DeSantis, back to work as governor of Florida after the spectacular failure of his presidential campaign, signed a bill banning the production or sale of lab-grown meat in his state. Similar legislation is under consideration in several states.

On one level, this could be seen as a trivial story — a crackdown on an industry that doesn’t even exist yet. But the new Florida law is a perfect illustration of how crony capitalism, culture war, conspiracy theorizing and rejection of science have been merged — ground together, you might say — in a way that largely defines American conservatism today.

First, it puts the lie to any claim that the right is the side standing firm for limited government; government doesn’t get much more intrusive than having politicians tell you what you can and can’t eat.

Who’s behind the ban? Remember when a group of Texas ranchers sued Oprah Winfrey over a show warning about the risks of mad cow disease that they said cost them millions? It’s hard to imagine that today, meat industry fears about losing market share to lab meat aren’t playing a role. And such concerns about market share aren’t necessarily silly. Look at the rise of plant-based milk, which in 2020 accounted for 15 percent of the milk market.

But politicians who claim to worship free markets should be vehemently opposed to any attempt to suppress innovation when it might hurt established interests, which is what this amounts to. Why aren’t they?

Part of the answer, of course, is that many never truly believed in freedom — only freedom for some. Beyond that, however, meat consumption, like almost everything else, has been caught up in the culture wars.

You saw this coming years ago if you were following the most trenchant source of social observation in our times: episodes of “The Simpsons.” Way back in 1995, Lisa Simpson, having decided to become a vegetarian, was forced to sit through a classroom video titled “Meat and You: Partners in Freedom.”

Sure enough, eating or claiming to eat lots of meat has become a badge of allegiance on the right, especially among the MAGA crowd. Donald Trump Jr. once tweeted, “I’m pretty sure I ate 4 pounds of red meat yesterday,” improbable for someone who isn’t a sumo wrestler.

But even if you’re someone who insists that “real” Americans eat lots of meat, why must the meat be supplied by killing animals if an alternative becomes available? Opponents of lab-grown meat like to talk about the industrial look of cultured meat production, but what do they imagine many modern meat processing facilities look like?

And then there are the conspiracy theories. It’s a fact that getting protein from beef involves a lot more greenhouse gas emissions than getting it from other sources. It’s also a fact that under President Biden, the United States has finally been taking serious action on climate change. But in the fever swamp of the right, which these days is a pretty sizable bloc of Republican commentators and politicians, opposition to Biden’s eminently reasonable climate policy has resulted in an assortment of wild claims, including one that Biden was going to put limits on Americans’ burger consumption.

And have you heard about how global elites are going to force us to start eating insects?

By the way, I’m not a vegetarian and have no intention of eating bugs. But I respect other people’s choices — which right-wing politicians increasingly don’t.

And aside from demonstrating that many right-wingers are actually enemies, not defenders, of freedom, the lab-meat story is yet another indicator of the decline of American conservatism as a principled movement.

Look, I’m not an admirer of Ronald Reagan, who I believe did a lot of harm as president, but at least Reaganism was about real policy issues like tax rates and regulation. The people who cast themselves as Reagan’s successors, however, seem uninterested in serious policymaking. For a lot of them, politics is a form of live-action role play. It’s not even about “owning” those they term the elites; it’s about perpetually jousting with a fantasy version of what elites supposedly want.

But while they may not care about reality, reality cares about them. Their deep unseriousness can do — and is already doing — a great deal of damage to America and the world.
