What you can do now:
Buy 3 complete blockmakers (with fuel cell) and 3 complete fuel makers (with fuel cell) [about 6K each] - don't know why you'd want to have three of each...but you never know...
Buy 7 cubimal boxes (5K each).
Buy the Nylon Phool Party (30K), invite your friends, and spend an extra 6K on food/drinks/party favors.
Buy a bunch of bags, fill them with stuff, and give them away to your closest friends or to newbs, or hide them in various locations around the game for people to find...
Buy one of everything that all the vendors sell and some of the things that can now only be purchased by other players (higher level tools) so you can get all the xp for discovering new things.
What you might be able to do later:
Street projects (as mentioned before).
Eventually maybe there will be more expensive houses than just the 50K ones.
Eventually, there may be options for decorating/upgrading your current home.
Keep it, and use it to do fun things for other glitchen once in a while. Though, realistically, you can spend 30k pretty fast doing that.
A cubimal gift here, a teal white triangle key there, and all of a sudden you're stuck with 8k and the distant memory of no-no powder, those two girls from Chakra Phool and an inexplicable auction receipt for thousands of planks. But there are no planks in your inventory.
