Who’s going to gather the lumber, pour the foundation, frame the house, mine the copper, install the electrical wiring, and all that shit? It sounds nice to say “maybe everyone should just have a house”, but houses don’t grow out of the ground. It takes considerable manpower, knowledge, skill, and resources to build a house. The people involved in that process deserve & require compensation. You can debate if it’s best to receive that compensation through a socialist system where they receive other goods and services in exchange, a communist system where everyone labors and receives according to state distribution, or through our current capitalist system, but it’s naive to say “just give everyone a house”.
