A lot of the problems that an ordinary person would suffer cease to be an issue when you're worth $2.7B. I suspect that for Thiel, the loss of hard fought rights will not impact him very much personally. Marriage for example is not just symbolic, it also confers rights to a partner's pension contributions, their assets if they happen to die intestate etc. Thiel may be able to fill many of these gaps with expensive legal arrangements that others can't afford.
