When I was a student, I lived in a flat above a shop on a main-ish road with double yellow lines outside, so nobody was allowed to park there. The only places I could ever park were outside other people's houses on smaller residential streets, where parking was allowed. They had equal opportunity to park outside their houses as I or anybody else did, but I was NEVER allowed to park outside mine.
I was mighty annoyed, though, when I had some heavy things including furniture to unload. I'd parked elsewhere and waited until 7pm and pulled half on to the very wide pavement (loading & unloading were supposedly allowed), so what traffic there was would not be impeded for more than a few seconds - and there was still plenty of room to get by on the pavement. A friend was waiting with the open-booted car and the police came and said I had to move it NOW - even though she told them we were unloading and would be gone in 5 minutes. What really annoyed me, though, was that the pub opposite would frequently have massive delivery lorries on the double yellows outside for half an hour at a time, during rush hour, causing big traffic delays. Nobody ever told them off, though. Yes, they needed to unload; but so did I.
It's nice if you can park outside your own house, but if all spaces are taken or parking is forbidden, then it's just tough. If it's important to you, you have to get a property with parking if you can possibly afford it, or accept that you have to lump it if you can't.
I'd love a back garden, but we don't have one. When we bought, we could afford a house with a garden or a drive but not both. We prioritised one with a drive, so we have guaranteed parking but every time we'd like to use 'our' back garden? Tough, we don't have one.
