I personally am ok with that.
What if they rent it out to the same tenant for 50 years? I am ok with that but start to question the wisdom of the tenant. What if rent keeps going up even beyond a reasonable mortgage payment? It doesn't make me question the landlord more. It makes me question the tenant more.
Now if you add a wrinkle like the landlord passes a law that no more houses can be built, then my prejudice switches. Or if it is more subtle like you can't build with the same kind of materials, or reuse a concept like footings.
I oppose that kind of rent-seeking. But it's not the rent-seeking to which I object. It's the moating.
Of course, it's hard to build a new house even without moating. I see too often people who just pay rent because it's inconvenient to look for alternative housing. And building their own seems way too hard. Their own creation would never have the bells and whistles of what they are renting.
Wells Fargo is a perfect example. You get cheated and abused and swindled, but you don't leave. Microsoft was an example for a very long time. Intel has been an example. Amazon is in a big way.
"There's no other option," people cry. But of course there is. Regarding Autodesk, FreeCAD is an option. "Not even close!" some claim. MicroStation? "No way." Solidworks? "Well..."
Build your own, rent from somebody else, go homeless, or stay where you are and pay your rent. And if somebody makes it illegal to do anything but the last, revolt. But don't claim there's no other way if you just mean you want to be entitled.
