@aral This is a pattern all the time.
Cars , religion, public land ...

There is a divide in perception between the two sides,
"takers" and "free spacers"

The notion amongst the "takers" is that if no one is using the space, then they can take it.

The notion amongst the "free spacers" (I am this) that the space has merit w/o being consumed by a human.

If you have 10 people looking at a pretty field in nature. 9 of them can enjoy looking at it, but one "taker" will ruin that for all.
