Decent analogy, but classic ham radio isn't a 'natural state' that's being encroached upon. It's just an older technology. I think a better comparison would be if the park had no cell signal, but did have an old pager network set up.

It works, but...ugh.

The pagers used to be extremely valuable...before better tech was invented. Very few people have a use for the outdated tech anymore. Cell phones let us do far more.
