Leaving it up to the cops discretion means they will be incentivized to enforce it against people who can pay but don't. This is what the signs say in San Diego. You CAN be asked to show your fare at any time. Meaning consequences for me but not for them. Except they don't have anything to lose so why bother? It's in their best interest to break the law and abuse the transit system for shelter, harassment, and committing more crime (spreading the heat == less chance of detection). I'll choose warming the globe any day over putting myself at risk of violence.
