Why would someone want a random block chain company to own 5% of the possibility of destroying their holdings? What if the company gets co-opted by some nation state actor? Bitcoin really seems like a terrible place to keep wealth.

I'm not sure I follow your question. Who is the "someone" you're referring to? And what do you mean by "destroying their holdings"? Even in a 51% attack, an attacker can't alter wallet balances or arbitrarily erase funds.

Also, what alternative "place to keep wealth" is truly immune to a nation-state actor? Cryptocurrency is actually unique in that, with something like a brainwallet, seizure can be made practically impossible.

If you own 5% of the hash rate you have ~0% ability to attack the network.

Yes, but if you're a nation state with dictatorial control over a nation's resources, +5% might be all you need.
