I can kind of relate to the feeling of IPv6 being "new and scary" to back in 1995 when I barely grasped IPv4 routing... everything becomes clear eventually with experience and exposure... hopefully eventually I'll understand more IPv6 concepts with time. I "want to believe". :)

But I do fully get that firewall without NAT is perfectly fine (great) in an IPv6 world - but may be necessary in simpler multi-ISP routing scenarios...
