1 - compare the govt and spacex track records. does that really seem wise?

The government let people on Wall Street keep their RSU style compensation after 2008. It's not like most engineers can sell their RSUs except on quarterly redemption days. Or the government could otherwise match the compensation. It has a lot of money.
SpaceX employees can't sell their RSUs period, since it's a private company. They're counting on a big payday at an IPO that will never happen if it gets nationalised.
