If i'm not mistaken, there is a structure you can spawn in that makes a bubble, allowing "enemy" (or in your case just players) to build in said bubble.
The command for said item is;
admincheat giveitem "Blueprint'/Game/Mods/CapitalismCurrency/Resources/Meshes/MarketAreaEnabler/PrimalItemStructure_MarketIronTorch.PrimalItemStructure_MarketIronTorch'" 1 0 0

This is found normally in the Capitalism Props Mod, but I believe you can also spawn it in with just the currency. Hope this helped!

Please use the MarketAreaEnabler for that. The item is called Market Iron Torch. closing...
