If things ever get bad enough that the wealthy need underground nuclear bunkers, the underground nuclear bunkers aren't going to be enough to protect them. The ordinary people who did the electrical, plumbing, security, etc. know where you are, and no level of security will protect you from an angry mob with nothing to lose.
I once saw a news article with interviews of anonymous bunker tenders; essentially, there is a small industry of former special ops folks that are paid to live in the bunker and maintain it.
The main point they made during the interviews: If things ever get bad enough for the owner to want to move into the bunker, the #1 priority of the guards will be to neutralize the owner. They worked out detailed contingency plans while twiddling there thumbs and rotating cans of caviar.
It turns out you cannot eat electronic money that’s sitting in the middle of a bank’s bombed out business continuity vault.

Governments around the world already keep many locations/facilities secret and hidden from the public.
They will simply arrest you, or worse, just kill you.

Those cold war bunkers only had one purpose: to keep high ranking government and military peeps alive just long enough (up to 2 weeks or so) to make sure that mutual destruction is actually 'assured'. They were not meant as some sort of cradle of a new civilization or as a safe haven to survive a nuclear war (because there would be no place to return to anyway).
