That stuff is really cool, the erector set for adults. You have built some really really nice stuff with it too. Ive actually used it before to build a support to hang aquarium lighting. But this stuff is so expensive that the average woodworker in this world just simply can’t afford this material. Especially to outfit their entire garage. I think its geared more towards industrial/commercial use.
I think an erector set for adults is spot on! In particular being able to reconfigure a build is a huge advantage.
In terms of cost, yes it’s not cheap. However, if you brought a few Husky tool chests, giving you probably less storage, you’d could easily spend a similar amount... that said those chest require zero time to build, I’ve spent a lot of time building mine
