The internet stopped being a network of peers where everyone needed an address and is now a split into producers (a handful of large companies) and consumers (everyone else).

The consumers are not expected to need a public address where they can be reached - in fact, having a public address is actually a security and privacy risk.

100% of consumer routers and OS level firewalls deny new inbound connections by default. There are upsides and downsides to static vs dynamic ISP-provided addresses, but the only difference between IPv4 and IPv6 in this regard is that IPv6 has a vastly larger address space and offers an ISP far more capacity to randomize a customer's host address for a far lower cost than IPv4. CGNAT is available for 4 or 6 if such is desired.
