Disclaimer: I haven't done cell culture in about 20 years.
My biggest question about lab grown meat is the cell culture required to grow it. In my experience almost all cells require some type of animal-based serum for growth factors and micronutrients in order to grow, the most common being fetal bovine serum (FBS). If these cultured meat cells require FBS, then they are still dependent on the meat industry and will likely be much more expensive than regular meat, espcially as FBS prices will increase as the meat industry decreases due to reduced supply.
I'm willing to bet that Trump could not pass the current one, much less a harder one.
