And that's way changings in basics of Nxt shouldn't be globally voted by coins.
There is no other way.
Another way: Voting power by some logarithm of fraction owned of all coins, weighted by account age. The latter discourages endless scattering of NXT to circumvent the logarithm (which would be a real problem in a naked log system).
Smaller, but older accounts could be on par with new big accounts in that system.
