No one feels like building. People just play videogames to unlock stuff online. Like for example people play TF2 for hats. People play GTA online to make a super cool car.
How about bricks cost score points and they are priced by the size of the brick (special bricks costs depending on the host). so a 64x baseplate would cost about 64 points and you can enable and disable what bricks are allowed to be bought through some handy admin gui or preference but I prefer a gui.
We already have score saver and a mod that allows players/bots/whatever to drop items which increases your score. So why not?
Now people can say "Hey, look at me! I'm so rich I made a loving mansion!" and they can prove it because it costs score points to make such a thing!
