I can construct many possible theories that underlie your claim but it would be rude for me to put words in your mouth and then reply to them. You’re welcome to offer an explanation if you’d like a second try. Though, I wouldn’t reply to ‘regulation has a special label at this one prohibitive extreme in specific’, which may save you a followup at least!
You can’t regulate the quality of things you don’t produce (or allow to be produced). You can’t regulate the sales of things you don’t sell (or allow to be sold).
