Is the migrant crisis contained to the city? do migrants venture beyond the infrastructure? couldn't you and some friends finance the restoration of an abandoned castle and rent out rooms privately to native born right wingers? As long as you have a road for the mail man and high speed internet, I think it could be kind of romantic in a rugged sort of way. Our Ancestors had to abandon the coastline and hole up in castles during the reign of the Barbary Pirates. There won't be any American Marine corp or British Navy to save us this time.
Good Idea but I think the state would use its police force against us. There are many reports from people who were thrown out of their flats by government officials, just to create space for so called "refugees". Landlords get more money for them.
Is it the state forcing the landlords or are they just offering more money to the landlords? If its the latter, you could include protective clauses in your contracts and if its the former, what is their criteria for deciding who gets evicted?
