Just take a look at many university networks. The ones I know use
public IPv4 space, no NAT and many times not firewalls. Now take one of
those scanner / printer thinks with anon FTP saving all document
scanned on their local disk drive. Or power full laser with a power
supply accessible via SNMP private. I think many people are accustomed
to the "security" they get from NAT and don't think that there is
anything else.
