If you don't understand the difference between a mask and a respirator I'm not surprised you misunderstand the surgeon general. Masks is to keep spit and the likes away from others (no it doesn't filter viruses), respirators are for filtering viruses, etc. in both directions (unless it has a valve, then it only filters air in, not out).
Unless you use sterilisation for your masks and respirators they need to be used only for short amount of time and you need to wear gloves when you take it off. If you just use it as most people outside of healthcare does all you are doing is wearing a Corona bomb on your face. Keeping alittle distance is much better and won't cause respirator shortage.
You are making quite a strong claim. Do you have any evidence for that? Why would getting some coronavirus on your hands when you take the mask off be worse than inhaling it? Of course many healthcare workers are being issued only one respirator per day, and they are exposed to drastically more coronavirus. It's not exactly difficult to simply wash a cloth mask like any other piece of clothing, and a surgical mask isn't very difficult to sanitize either.
Moreover if you are sick and don't know it a mask protects everyone else from the primary infection route.
