It's not a terrible example. You can have delicious vegan food and you can have moral objections to the process of eating meat.
But if your reasoning is to enact some larger impact on climate or the practices of industrial meat production your own consumption habits are mostly irrelevant and you should focus on regulating those things instead.
The difference is that food isn't a licensed product. You can have very sustainable meat at home. You can't source sustainable Mario Kart.
"I asked cocaine to make me a birthday card for my nephew. It's not as polished as the one I bought in the shop, but the cocaine one was a lot cheaper"
It... may not cover every scenario.
"I refuse to watch that one Argentinian TV show that has a shot made with some cocaine". Better, but bit harsh. Maybe there's some value to it.
"Cocaine is fairly practical to tell me things I can verify at a glance, but I wouldn't trust everything it says". See, that one works worse that the real one.
