In many countries that aren't the US, if you show up at a hospital with no cash and no insurance, they show you the door.
That's one way to do it. I've no problem with it either, provided the potential patient does not have a life-threatening condition. That would end the freeloading right there.
I don’t believe in not treating patients who will eventually wind up in the ER with a life threatening condition. That is not what we should do as a society.
What I do believe in is having insurance cover conditions that are life or limb threatening- CHF, diabetes, cancer, heart disease,trauma, etc.
The rest not on the list- you pay for out of pocket.
You want your hay fever treated? Pay for it out of pocket.
Same with erectile dysfunction. Pay for your own Viagra.
You want a scooter? Lose weight, you may not need it if you lose a few pounds, if not- pay for it on your own.
Insurance covers too much.
