Apparently, we buy NXT as we buy stock from a company. So 1 NXT== 1 Vote is more reasonable. 1 Account == 1 Vote is nonsense because account can be created freely and rich people always can split his account into lots of small accounts. 1 NXT == x Vote is also impractical. we can't decide which NXT has more weight. yes, give rich people more power is not democracy, but is the way a real company run.
Well this is not a company, you bought no shares from no shareholder. if 1 acc= 1 vote is nonsense, then 1nxt=1vote is even more.This excludes everyone at all. Do not get shareholders and stakeholders mixed up now
What you are saying is: "ok, with 1person=1vote so many accounts can be created and i do not know how to avoid this, so ill go ahead and hide it under the carpet, and forbid voting for everyone who is not a millionaire."
There have been interesting ideas on the table. 1 zillion Nxt = 1 zillion votes is not one of them.
If you are going to rig the system from the beginning, dont rig it towards the millions, rig it towards the newcomer in the market.
