You are 100% incorrect on your first point. Selling a home is not easy nor cheap, takes time, and is wrought with uncertainty. It's usually a low liquidity environment.
On the renting side, terminating a lease early is generally trivial. I've terminated several of the leases I've signed over the years mid-term by finding a new tenant for the landlord beforehand and having that person take over or sign a new lease. Landlords are usually happy to do so since they can increase the rent without losing any income.
I guess in the end I just like to do what I want to do and not have to ask for permission or get approval.
I purchased our offices and wanted to install a door and just did it. I want to put in an alarm system I know it potentially adds to the property value. New carpets? Sure since even if we move it has value to a new owner (not 20 years later of course...) I didn't have to clear it with anyone and I didn't have to think about all the fine print in a lease or anything else.
