The fundamental problem with your argument is the assumption that government services are offered in exchange for tax in the same way that you pay for other goods or services. They're not. The very nature of western society is that it doesn't offer value for money to the richest. This is by design. We've built progressive taxation systems as a way of redistributing wealth downwards, providing benefit to the whole of society rather than just the few with the most. How many countries have you lived in? Why did you choose the place you live now? Presumably you have a spreadsheet somewhere with the tax to service ratio for all the countries you considered? Well, maybe you do. Most people don't. Most people live in the country they were born in, or perhaps emigrate once to a country they perceive to have more opportunities (or family, or a more stable government). The only people who are shopping around for the cheapest tax regime are already exceptionally wealthy and looking to keep more of that wealth for themselves. They're not looking for any governmental services, just a way to stop paying for those that help other people. Maybe that's OK for you if you're heartless sociopath. It's very easy to forget just how reliant we are on the hard work of other people, even those who earn far less than us.
