Still not following - if I choose not to go to the hospital, why do I need to sign a waiver first saying "I will not go to the hospital"? I just won't go.
As noted, it simply is not a matter of "putting myself in danger". I could be one of the 10%? 20%? 50% of people who can be asymptomatic carriers of the virus. If I go to a "nightclub, restaurant, gym, whatever", I could very easily infect dozens or hundreds of other people if I'm infected and don't know it.
I think I kind of see where you're coming from, and if it really were an issue of "I'm willing to put myself in danger" I might agree, but that is not the case. My going out endangers the lives of many other people, waiver or no waiver.
