The existing supply of price control failures is quite large. I’m guessing a strategic release of a new example will likely not have much of an impact.

It's pretty obvious that there are a lot of people who don't get it, because in many cases the consequences aren't as easy to see.

You stop landlords from collecting rent, set that precedent, and over the next few years they're going to convert rental properties into condos until rents are high enough to account for the risk of it happening again. Then anyone who can't afford to buy is paying higher rent for a generation or more. But it doesn't happen instantaneously and it's hard to trace directly to the act, so people don't understand.

Set price controls on gas and there immediately won't be gas to buy. That's something everybody is promptly going to notice.
