What protects your BIOS/FW? What protects your hypervisor?
OK if you are an idiot with only 1 PC don't do it. I agree
at this point everyone here should have a few throwaway laptops lying around for sacrificial moments. no hd or wireless, use a live cd on r/o optical if you really want to inspect random flashdrives. even then it can get a persistent infection that survives power cycling.
