Banning the ability to legally make a choice is effectively the same thing as banning the choice itself. It doesn’t matter if you’re legally allowed to consume something if it’s illegal to obtain it.

For example, I’m in VA. When Democrats last had power they legalized possession of Marijuana, and created a path towards establishing legal vendors. When Republicans took over, despite saying they wouldn’t do this, they removed the path to create vendors, so it’s illegal to purchase. It is technically still legal to grow it, but that’s the only legal option, and it isn’t an option for most people. In effect, it’s almost as illegal as it was before.
