Are you saying, without NAT or something like that to restrict
reachable ports, the Internet, regardless of whether it is with
IPv4 or IPv6, is not very secure?

With end to end NAT, you can still configure your UPnP capable NAT
boxes to restrict port forwarding.

Want to run a server at the hotel?

IP mobility helps you, if you have a home agent at your home and
you can use IP over UDP/TCP over IP as mobility tunnel.
