"The problem I have with this is that these people contribute absolutely nothing to the community"

They pay taxes and consume very few resources. Their property taxes help fund all the municipal services while not using the schools, placing little wear on the roads, and most likely not being a social burden requiring EMS and law enforcement involvement.

"and do not even communicate with the people who actually live here."

Why do they need to communicate with you? Given your attitude towards them, perhaps they communicate with others...

The horror, someone who owns 10 acres wants to put up a tiny house and rent it out to people who will come to the community and spend money locally, the nerve people have hoping to use things they own to better themselves!

Humph, I'd move to Canada!
