Yeah if you live on 70k in my home town that is far more than just comfortable. I actually know of people who can take remote jobs with a high salary then move to less wealthy countries to just become the top 1% there also.
I don’t know, people find reasons to be unhappy. Supplying your baseline needs could certainly alleviate stress and help keep you content, but without purpose beyond themselves there tends to be a trend of disillusionment and depression. It’s no secret the amount of substance abuse is prevalent in wealthy families.
They could now if they wanted. Most lakes are government or private property. You think they’d want to lose profit margin?
Not to mention the massive difference again, the wellbeing of other people. Houses are crafted by skilled workers, it’s not a right to their labor, nor a right to the owner’s property who purchased it after it was built. You do however have a naturalized right to survival.
The point is, property taxes are fine but saying “um you should be forced by the government to use something you own in a specific manner” is nonsensical and authoritarian overreach at minimum.
I can still buy a car and have it just sit there. The driving part is due to affliction of other people’s well being. Me raising the money to buy a house and deciding I want it as a summer stay location, so I leave it sitting there while I’m somewhere else would have no harm on another’s life.
