This is falling outside of the IPv6/RFC-1918 discussion, so
I'll only answer questions with questions... If there's need for
a real discussion, I'll let someone change the subject, and continue

Why do I need an "Internet breaker" (firewall) to do connection
tracking? Doesn't the host computer's software stack do that when
an inbound packet arrives? Why do I need a separate box to do that
work with I trust my host?

That's an issue of trusting the host...
Note: All questions are hypothetical. No packets were harmed in the
production of this hyperbolic response...
