Exactly. By the time they manage to make this feasible on a large scale Americans won't be fat anymore because liposuction will be much cheaper.

Where would they get the fat from? Would vegetable oils do or would they have to use animal fat? Can animal fat be synthesized in a similar way or would butchering still be necessary? And if they add the fat later wouldn't they be consigning this meat solely for use in burgers (and sausages, meat pies maybe a few other things)? The goal is to produce this stuff cheaper than meat so that might not be the worst thing but at some point they might want to produce higher end things like steak and then some marbling research would have to be done.

making a steak would be much harder, because you have to mimic structure in addition to composition.
