Wouldn't highering the number of consensus witnesses and applying the example you mentioned before allow the community to get few spots? 100/30 (or lower value with each vote) + limit number of votes / will give us a value than can be easily surpassed by some current whales to push many users to the top. What do you think?

The goal is to make it harder not impossible. We will always be in a situation where one or two people are controlling the top 20 spots, which is already the case now. If we nullify the stake of X the one behind it will again become the new player. But I guess this is a natural thing on a DPOS Blockchain.

Tron didn't mention if they brought the whole package (I mean all the Steem in all the accounts) but I can't see them sending 100 to null just for the sake of it.
