It seems a little odd that other crops have been cultivated to literally suit people's tastes and interests, yet many trees...Seemingly not as much?

I recognize the growth cycles are much longer, in some(many?) cases far exceeding individual human lives, but whole civilizations have been relying on trees for ages. Have none, not even isolated parts of them, been stable enough to take on this experiment?

Basically, the molecular architecture of photo synthesis evolved in the absence of oxygen. It is severely inhibited by the presence of oxygen. Same goes for the enzymatic reaction to fix nitrogen. Basically oxygen fucked everything up

However oxygenic respiration is far more effective. You get way more atp bang for your rubisco sugar buck doing oxygenic respiration.

Likewise, you are splitting off oxygen as a terminal electron receptor in photosynthesis. So, shits just around.

Saying you are going to hack or solve photosynthesis us a great sales pitch. You can get a genetics company funded saying this, many have. But realistically, if anyone did "hack" or "solve" this (as if it's a problem needing solving), it would be a disaster. In the time period when plants had figured out photosynthesis and lignin, and before wood decomposing fungus, we had glaciers basically to the tropics. Not to mention, well, oxygen. You just aren't going to beat oxygen.
