“Start-up cities” for refugees: a long-term solution to the refugee crisis?

I propose to create what I call “free havens”, which really are newly created cities, governed by officials from countries with a high level of rule of law, and where any refugee could go to. This idea is very similar to the concept of “startup cities” or “private cities”, whereby cities would be created by private investors from scratch in a bid to create a much nicer place to live than in existing cities and to provide a more beneficial investment climate by offering a much stronger protection of property rights than elsewhere. A territory should be rented from a state, similar to how the British leased Hong Kong from China for 100 years, but this time a fair price should obviously be paid to the landlord.

This is outrageous. Inviting an invading army into your country is treason; giving them territory is asking to be enslaved.
