> So if some plurality of rich stakers wanted to do a hostile takeover of a network, the community could create a fork where the oligarch coins are frozen and continue from there.

What's the "community" here? What would incentivise users to consider the new fork to be the legitimate one? If rich oligarchs control the first one - how do you build trust in the new one as opposed the current one? As a fiat currency - I would assume the rich oligarchs would have a great chance of leveraging wealth into ensuring that the current coin gets marketed and hence holds trust? The USD holds its current position because the US Gov stands behind it - what would keep the oligarchs propping the current coin up as opposed to the forked coin?

I'm sorry if this sounds silly - as I'm not very into crypto.
