How will they maintain a firearm by mandate if they don’t have one?

They don't maintain it. Nor does it say anywhere in there that anyone and everyone drawing breath must purchase something.

I highly recommend you stop to think it through next time before posting the first thing that somebody hands you. It could save you from looking like a complete fool.

Maintain means OWN not take care of.
