So basically: instead of just having what you need, just, like, hope that your neighbour has what you need. Great plan, i also hope that the neighbours are going to always follow me (just in case i'm going to move elsewhere).

"Sure you'd have to logically create 'centers' around town close enough to walk, or have a neighbor maybe deliver if you're elderly or something, but there's convenience in having more options if you don't have a specific tool and only need it once." or just have a garage or a shed for tools.

"Now that you don't need your own tools, lawn mower, 3d printer, printer, atv, weed whacker, you find you could've done without even having a garage, maybe we can start building smaller homes that are cheaper to heat or cool and with less environmental impact." ah yes, the number one reason people get large homes: forget having family or simply enjoying spacious living conditions, i'm storing all of my tools around my house.

"Some sort of share/rental thing maybe for the atv's, and boat/rv storage." Good luck proving that the ding on the ATVs fender was done by your neighbour and not you.

"Commercial kitchens and space for community get together's, I grew up in the 80s and we knew our neighbors back then." Why can't you just invite your neighbours to your house?

"... been conditioned to think we all need to own so much shit, when really we don't..." or perhaps some of us are conditioned to think that we don't need anything, that everything should be rented/lended by a neighbour and basically make your house into a shed because all you do is store tools anyways.
