Yeah, totally. Once it's both no longer insanely expensive and approved as safe, of course. I'd still buy it even if it cost more, within the realms of sanity.
I have no problem with eating meat and animal products in general. It is the most bioavailable way for humans to get their nutritional needs met. I am a pretty light meat eater just by nature and probably eat vegetarian 4 or 5 days out of the week, but if my body says that's what it wants, then that's what I have. Usually fish, but occasionally land animals.
But I do have a problem with the disgusting and torturous sorts of environment most farm animals live in. And I already pay more trying my best to avoid them, but fully aware that even some more humane farms aren't that great.
Furthermore, I have a cat, and cats are obligate carnivores. Yes, I also try my best to check where her food comes from.
Getting lab meat basically eliminates all that checking, or the uncertainty of whether something really is as advertised, from my life. I'd be all over it.
