Building/refurbishing furniture, working on cars, basically anything that is loud and requires power tools and space to lay out, assemble, or store materials, also gardening.
this is all stuff that in Italy goes on inside the city. There are fab-labs, maker-spaces, communal gardens and other communal organizations that enable you to do this without living in bumblefuck nowhere or renting a giant ass house.
There are garages underneath the apartment lot where you can do reasonably noisy work from 7:00 to 23:00, no need to go to a maker space or anything like that
Have you ever worked in a shared space? I have, and shit was constantly being lost, broken, or stolen. More people just means more chances some asshole will ruin things for everyone.
omg you're so American. These places have clear rules, systems to guarantee accountability, with software tracking every person using a room or a tool at any given time. They are managed by people that work there full-time and guarantee everything is in order.
All of those things can be done in a densely populated city. I do it and live near the city center in São Paulo, the world's 4th most populous megapolis. In short, your arguments are bullshit.
In 'murica it may be impossible (thank car-centered infrastructure and your insane zoning laws!), but here you can just rent a house instead of an apartment... an OK place (2+ bedrooms/ 150+ m²/ space for tinkering) at an OK location (safe enough, relatively close to the city center) is ~600 to ~800 USD, which is certainly more expensive than the local average, but not eye-wateringly so.
