I fear and hope that it’s impossible to find that out.
If somebody purchases half of the shares (actually half of the minting shares is required) that person owns half of the corporation.
Wouldn’t you agree it’s ok, that the person with half of the stake in this corporation is allowed to decide just as a distributed majority is?
That is bad in terms of centralization, but in economical terms it’s ok.
The ones who own, run the network, decide.
That much is true for Bitcoin as well.
But Bitcoin can only come to consensus at controversial topics through forks, deciding which software version to use - NSR holders can vote in more elegant ways.
