Innovations like this entirely miss why housing is expensive and out of reach for most people. We have more housing than people already.
This doesn't address corps like Blackrock buying up housing in bulk in order to dictate market prices. It doesnt address the wealthy buying up property as a way to avoid taxation on wealth even when they have little intention of using it. It doesn't address legislation that prohibits high density housing or mixed use real estate. It doesn't address plummeting buying power because wages have plateaued for decades while inflation keeps rocketing up.
So until that and more is addressed there is no construction innovation that will make the housing market more affordable.
