Um, yea honestly removing parking garages has been a huge boon to many city centers. Cars also take up a lot of street parking space that could be used for a lot of other things, too, including just expanding sidewalks(I mean goddamn 5’ minimums with stuff periodically in the way is just ridiculously tight.
A proper metal shop is fine, but it would need to be in a space that could accomodate it with all the necessary fire safety. I’d say for the sake of giving you a stronger argument we’ll go with a woodshop. I’d also love one, but it would also be fine if the facilities were available publicly in some fashion. Some buildings would, of course, still have garages or sheds in their backyards and that would simply be something you’d need to luck out on but shouldn’t be expected as available to every home. Many people simply get a shop space away from their house they can go to to do the work.
The reality of it is that if you want space you don’t get to declare that you’re entitled to it wherever you want to live. Space use and density in a neighbourhood are incredibly important to making sure that people can thrive and if those are compromised for inefficient uses such as everyone getting a mid-sized garage space it starts to break down.
I live in a mid-density neighbourhood and everything I love about it is because it’s not bloated by sideyards and garages. So yea, my car is in the elements and I cut wood on my front porch but that’s just how it goes. If I want a table saw that bad I’ll just get a folding one, move my car back a little bit(and probably cover it with a blanket) and work in my little parking spot that I pay extra for.
