If an individual founder, group of founders or guild / clan wants to create something consistent or town planned on a grand scale then I think the solution is to rent your own world. This will give you clear control over who can place beacons. It’s your world - so your rules. You can black list a previously white listed player. And likewise players need to understand what is possible when they start getting access to another group’s world.
On the public worlds I dont think we want anything that allows players to dictate (in a friendly or unfriendly way) how other players need to play the game. Consistent styling or design needs to be opt-in. Public worlds means playing together with everyone equal.
In the past there was a discussion about Beacon fuel and a range of player voting systems and suggestions - but all of them seemed to be open to abuse or were extremely complicated.
Just thinking out loud, there maybe a system where players or clans can reserve larger areas as a multiplier of their current beacons capacity. This would allow them to “soft” claim what they want for future developments. These “reserved” plots would still be wild, but could be reserved from other players claiming them. This would stop players moving in, unknowingly blocking a project you had planned.
Alternatively make sure you claim all the plots you need up front.
