The point is that PoS can't be secure (see my post upthread on that) and politically it can't honor the wishes of the common stakeholders (thus arguing they should set policy is entirely vacuous), just the same as how democracy is a total sham.
Some Iron Laws of Political EconomicsPeople are hoodwinked by PoS for the same reason they are hookwinked by democracy. Both of which are complete lies.
Here is what will happen to both every time...
Bitshares ... people will even stab or murder each other eventually ... It's also going to have elements of corporate fascism
Representative government has always and will always resolve in megadeath and catastrophic failure.
I understand your shorting attack vector for PoS. I just think it is unlikely.
I'm not arguing that PoS honors the wishes of the tiny stakeholders. PoS honors the wishes of the dominate stakeholders. They set policy.
