Like water spilled on the ground, which cannot be recovered, so we must die. But God does not take away life; instead, he devises ways so that a banished person may not remain estranged from him. 2 Sam 14:14
It's not a free action like the Mausoleum, you just get to build something you would otherwise not have the resources and/or would have to pay for. If you are low on resources, it could be a great deal, though.
