Why does DeSantis hate the free market? If lab grown meat is so disgusting then consumers won't buy it and the problem takes care of itself.
Because no one actually cares about markets.
The left cares about creating equality. You think Communist revolutionaries (the ideological ones, not the power grabbers) cared about economic theory? They thought they were having a revolution in favour of equality (spoiler alert: didn't work out so well). The anti-free market stuff was because markets allowed a lot of power to accumulate with the rich, but the modern left as figured out that it's far better to work with and regulate free markets than to try and destroy them.
The right cares about creating order. And nothing creates order like a strong leader with the power to act. That's why they loved free markets, because behind each business was a strong owner giving clear directions. But then businesses started taking directions from various internal committees and there no longer seems to be those strong leaders with the power to call the shots (at least in the way they like it). So now it's the job of the strong leader in government to step in and right the course.
Just look at how the right is enamoured with Trump. It's not because of his policies or managerial ability. It's because he clearly doesn't take direction from anyone and therefore qualifies as a "strong leader".
It's also why DeSantis is a complete dud, everyone can see this stuff is transparent politicking and nothing says "strong leader" less than a weathervane.
