Do I particularly care if the Rams come to Los Angeles? No. Do I think that most owners would poo poo the plan? Probably - with the greater Los Angeles area being unaffiliated, all franchise merchandise sells quite well. When Los Angeles has a team, stores tend to stock mostly the local team's logo wear, which doesn't sell quite as well as the entire line does.
As well, Los Angeles not having a team is a massive stick to wave at cities to say ‘hey, do what we want, or we'll move to Los Angeles.’ The only leverage that cities have is that there's no available skybox ready stadium in Los Angeles. Sure, the Rose Bowl could be adapted, but local regulations that limit the number of events would pretty much preclude a franchise being based there. This is changing - there will likely be at least one built in the next five years.
But he plans to built them a new stadium. That’s quite a gift for an unaffiliated city.
