When you reach a certain level of wealth, you'll begin to view your government more as a service provider than a community to which you belong (you're hyper-mobile so the world is your community). You can certainly afford to shop around, if you're willing to take the rough with the smooth (e.g. lower taxes under one government but perhaps a higher cost of living). A strange but (I reckon) valid analogy: imagine if your first ever laptop had been a Dell. Using this laptop you made a fortune by starting a tech company, and with your newfound riches decided to buy a MacBook. Should Dell be angry with you because you used their product to make a boatload of cash and then left them high and dry? No. There was a contract in the first instance which didn't specify a lifetime commitment, and you never stepped outside the bounds of that contract. You gave them their money when you bought the first laptop, and that was all you owed them. In terms of governments, Eduardo Saverin had been paying US taxes for his entire working life. The system provides a strategy for opting out, but he's now paying an exit tax and he's lost any benefits that US citizenship and residency brought (like TSA patdowns and pepper spray incidents). If you believe in making citizenship irrevocable, coupled with the global US tax burden (US citizens have to pay US tax on their worldwide income regardless of where they live), you'll put off swathes of future investors from coming to the USA. You're basically sending out a message that says "we're so paranoid that you'll leave that we're going to imprison you here"—like glassmakers on the island of Murano.
