You can't do that if they don't sell and they won't sell untill bitcoin stores large portion of world's wealth.

> I assume 'fair' to you would mean taking it from them to re-distribute between everyone else?

I have no idea why would you assume that. Especially if you could achieve same thing just by destroying their bitcoin. No need to re-distribute. Share is the thing that matters not the amount.

On more serious note fair for me is more or less how actual brick and mortar econony distributes things. You make things other find useful, you get share of humanity's wealth in return.

Holding things, bitcoin, gold, real estate, copyright strays for me from 'fair'. I see it as the less fair, the less you contibuted to humanity to acquire those things and the more claim on share of humanity's wealth you have by holding them.
