Very true.No doubt. But still someone's got to do it sometime. If Jim Gremel wasn't doing it you wouldn't have had the opportunity to make that great little tree from great stock. I hear ya but the more people starting long term projects from nothing the better I think. If we want to have really good stock to work with in the future without relying on yamadori collecting people should be starting stock now with the idea of just conscious development growing for 20years like yours. Or even better 40yrs. The thought of doing that does appeal to some people luckily.
If I could find a shimp start like yours for 200 I'd be all over it of course but I'd still want a space to grow out smaller younger stuff. If I had to for some reason chose to have/do one or the other it would not be an easy choice.
But, the OP was taking a rather young tree and styling it, and then hoping it will grow into a more substantial tree. I believe he said something like he was planning to leave a lower branch on to thicken the trunk. But, it’s in a bonsai pot. It will take forever! Trunks don’t thicken in bonsai pots. Not rapidly. If he wants a substantial trunk, he needs to put it in the ground.
