I agree that we need regulation. But I think you also discount the effects of individual consumption.

In the long-ish term, the animal farming indistry has to go. It cannot be made sustainable, no matter how you regulate industry. It's just a waste of resources. So at some point you as an individual have to adapt to a vegan diet, either by choice or because there is no alternative. What will it be? Do you want to stop eating meat the moment it is outlawed?

People who cling to eating meat nowadays actively oppose regulation. Otherwise they couln't eat meat. There is still a demand. We need both regulation to end animal farming and convince individual consumers, that they have to become vegans. It's the masses who have the most power. If veganism came from the majority population, it would be far easier to regulate industry.
