The point isn't for "first responders" to be paying for masks out of their own pockets, it's for the healthcare system (i.e. ultimately insurance companies) to pay higher prices so that more masks are made available to first responders, either by stimulating new production or reallocating existing masks.
If you just start confiscating them then anyone who did something we very much would like them to have done right now -- stockpiled a lot of such equipment to profit in just such an emergency, thereby causing such a stockpile to actually exist -- would see what you've done and choose not to do it anymore. And then next time the shortage is worse.
