I don´t play a lot anymore, but just came to say i totally agree with this, and support the idea everytime it pops up in the forums.
PvE servers are often filled with buildings not being used and in the nicest places. Some of them are huge and there is no real consequence for occupying tso much space, that´s a mayor flaw in the game design too.
If any player play constantly wouldn’t have any problem keeping their bases from decaying, and if they build huge they better play a lot in order to get the resources to maintain it… that´s only fair.
For those amusement parks and roads, is not like the floor is lava you know? at least for the most part… they´re also ugly and annoying, for they take so much good space for actual players.
For PvP servers sounds like agood idea too, that way players can´t hide in their bases all the time…
So for all i care, this is the best thing that could happen to the game right now… and just because it has been so long since we are asking for it…
