It may be his memstick, but when it is mounted, it becomes one of the
filesystems available to the operating system. If a user  decided they
wanted their memory stick to mount somewhere under "/etc", they could
simply subvert system security, controls or existing configuration. This
is why a mount should require system authorisation. This is fundamental
security and trading it off for convenience is just that - a trade-off.
It is your decision - just be sure  you are aware of what you sacrifice
for the convenience.
