The idea is "Governance as a Service", you sign up in a city to either live there or start a business, and enter a contract which is also the permanent law, no unilateral changes possible. Taxes are nonexistant, instead you pay a yearly fee. The city guarantees security, infrastructure and so forth, and that's it. Your disputes with the city are subject to common law and would take place in front of international arbitration courts.
