Let the containers on the streets piss people off to build pressure to align incentives, rather than prolonging the problem with a temporary stacking improvement. This is just a tool in our toolbox that we should not ignore, I'm not saying it's the right tool. But there is a cost of papering over the root cause, that's not free.
BTW I don't live in LA/Long Beach. I recognize that LA doesn't deserve the quality of life degradation, that's an externality. We have tools to resolve externalities. I could imagine living in an affected neighborhood in LA and being super grateful for the container stacking "quick fix".
