Something makes me think that that particular location doesn’t have abundant legal parking options available, which in turn is a community problem. I’m not defending her, but it’s a two sided coin.
Why is it the public's responsibility to provide and offer people space on public right aways to [temporarily] store people's private property?
There's a common benefit to having spots available for businesses and other uses. Its sort of why we have parking meters in the first place, so people don't camp spots all day long.
I get this. But this isn't a community problem. It's a community choice.
For free mind you (at least in this case)
For the same reason it's the public responsibility to provide infrastructure to get private property from A to B (roads), protect people's private property (police, military, firefighters), etc. It's just infrastructure.
