No you wouldn't. You'd hit the next impediment where the presence of
IPv6 on your LAN destabilizes your "Internet connection" by causing
all your software to try IPv6 first even though the IPv6 network
hasn't reached the level of stability present in the IPv4 network. And
then you'd stop and (rightly) complain about that problem too.

How many zeros would you like at the end of your address count? The
smallest ARIN IPv6 assignment has nearly 300 trillion more IP
addresses than the whole IPv4 Internet.

You've misread the insider terminology. Here's a brief lesson in ARIN-speak:

allocation - addresses provided to ISPs which ISPs then "reassign" to
customers. These cost a lot per year. Partial waivers apply until

assignment - addresses provided to end-users. These cost a lot up
front, but then the organization as a whole only pays an annual
maintenance fee of $100 per year total. No waivers apply.

It still is on every analog line I've tried, including voip adapters.
