The biggest problem with laws is that they protect the rights of some, in some cases and other cases they are just completely asinine, but they also infringe on the rights of others. The protection being offered by any of these laws is the illusion and entire point of the discussion. If someone is mentally unstable or disabled to the point that they are incapable of comprehending the laws then it's ultimately irrelevant because they first and foremost have no comprehension of what they are supposed to abide by and secondly don't have the capacity to determine if their actions do or do not comply.

It's obviously not an easy situation to deal with these problems, but any illusion that a law is protecting these individuals or us from them is just more separatist fear based logic. A person couldn't be incapable of comprehending and complying and also capable of benefiting from a law so it's essentially the same as police reading Miranda Rights to a criminal that doesn't speak English or know the laws.

The government has no need to protect or permit anything if they aren't the one giving you the right in the first place. All laws are fundamentally built off the original concept that it's the governments sovereign duty to give you the rights you are born with. If this entire bureaucracy didn't exist in the first place, the laws would never exist and the whole discussion would be pointless. I would argue that being born gives us all an equal right to exist and that simplifying all of the technical garbage created by the legal system to give out illusions of necessity or benefit from their existence is really just no different than telling children Santa Claus is real or the Easter Bunny exists.

Perhaps giving people the illusion of safety is really the problem in the first place. I would argue that telling people they are offered any real protection because a law makes something illegal is giving them a false sense of entitlement. If someone feels that the government is responsible for their well-being then they aren't as focused on becoming self sufficient and capable of sustaining their own existence. Perhaps with a stronger sense of community and less scarcity based mindset taught by the education system people would be more willing to help each other and realize that we are all responsible for ourselves and SHOULD feel a moral obligation to share and help those that can't help themselves so that those that are sick, disabled, elderly, mentally ill, or for whatever reason incapable of caring for themselves are also our responsibility because we should respect their right to exist as we do our own.

Edit: You are right about the massive stretch statement. I can't expect to hold myself or others to a different standard, but at the same time it's obvious not everyone is concerned about the reality of the situation. There is always going to be the issue of when the majority decides to stop accepting these "laws" as acceptable or necessary and it probably won't go over well. Slowly over time with discussions like these, the changes that are occurring in movies, music, and society will hopefully create the situation to start these changes over time. I have never been pro violent revolution and I feel like the only real revolutions are the ones that take place in our minds.
