A few points,

If there is not a strong belief in the product the person holding 6% has the agency to dump their entire supply. I am no mathematician, but seeing 6% of an entire ecosystems supply getting dumped has huge bearish connotations to it.

You also have to factor in a large portion of your air drop will be dumped as well.

If a certain percentage of the tokens are locked up in someone's account, it is drastically important for them to be an active member of the community. Say in an extreme example, someone is holding 10% of the supply and is inactive. If that is the case, our proof of brain model leads us to the conclusion that the productivity of the network is limited to 90% of the circulating supply. In that case, everyone on the network will be harmed.

I got to disagree here, if someone holds 10% of the tokens and does not vote, that's a gift to the community. That user is not taking his fair share of the inflation and letting the community have it. I don't see any problem with this at all. My only concern is any one person having too much power to put the ecosystem at risk.
