Does it have to be one or the other though? What's wrong with funding projects such as the impossible burger until lab-grown meat is economically viable?

I feel like your position is analogous to saying, "I think it's better to focus on nuclear fusion. Why waste time working on renewables?" Of course we'd like to power everything with fusion, but it's not there yet economically or technologically. So in the mean time, it's probably a good idea to also fund intermediate solutions.

Could you explain this stance? Precisely what do you find objectionable about other people choosing to eat plant-based foods that happen to imitate meat?

Edit: I see your position against the meat substitutes is primarily health-based. Almost certainly it would be harmful to one's health to consume foods such as the impossible burger frequently, but you should consider that the products that it's trying to replace aren't necessarily any healthier.
