Not my claim at all. My claim is that a senior professional (in _any_ field - not just a senior developer) doesn't care about the cost of rent. It includes your scenario - of course you should be able to rent and move about if you want to. If the cost of the rent is heavy on your mind, your position is not that of a senior professional. The title has become meaningless because it's effectively become an entry-level job. (Externally it looks like in SF, real entry-level jobs result in, well, homelessness or living in a van or something).
