Imagine: if half the single family homes were replaced by duplexes half the neighborhood could be green space ("natural settings")!
From an environmental perspective there is no contest between single family suburban development (aka sprawl) and dense urban living with plenty of parks.
Also, you won't find bigger bike/transit activists than the people advocating for the abolishment of single family zoning.
Of course it's a universal right. I don't think there's an idealogical gap between us on that front.
The other side of the "or" is a particularly egregious example of the excluded middle (separate from the missing middle housing shortage). The idealogical gap, if anything, seems to stem from willingness to believe that supply and demand affect housing affordability. I believe they do. The "regulations making housing artificially scarce" are exactly those inhibiting supply.
To that point and your question---of course landlords will always raise rent to the extent that the law allows it and the market will bear it.
