>other people will solve them
Other people are solving the real problem of address exhaustion, just not in the way that the IETF intended.
Even the IPv6 enthusiasts accepted that adoption would have to be widespread before the regional registries started running out of IPv4 addresses if it were going to work as a solution. That hasn't happened and it's now just too late - don't forget this started 22 years ago when most of the host systems were still under the control of education and government institutions and migration could have occurred much faster than it could now.
The thing that still irks me is that there'd been a very similar and very public (though much less protracted) attempt to deal with similar address limitations in DECnet that had failed miserably and the IETF chose to turn a deaf ear to those experiences which have simply been repeated on a larger scale with IPv6.
The problem of address exhaustion remains. IPv6 is no longer the solution, it's time came and went. A different group of "other people" are now attempting to keep the Internet roughly connected, but I'm afraid end-to-end connectivity is gone because the solution that offered it has failed the acceptance test.
