I agree, fuck cars, but cars won’t disappear and be banned overnight. Even if we begin getting rid of cars one policy at a time, parking will still be a requirement. I live in a country without any parking requirement laws (no laws at all really), and the roads are uhh… interesting. Even nicer areas have roads that feel like slums because everyone is parked all over the street.
As others have worded it, it’s a hobby. Self hosting is only necessary for a very small number of people, less than one percent of people on here, but it’s a fun hobby, and I’ve learned a lot about software and networks from messing with self hosting stuff.
