This is not a whole solution, true.

why would anyone demand IPv6 until there are any IPv6-only resources?

Have you actually read what I wrote? IPv6 promised "end-to-end connectivity". You can use end-to-end connectivity for a lot of things besides accessing public IPv6-only resources. You can access your own resources: console in your living room, NAS with your collection of MP3s and videos, etc.

Sadly IPv6 in it's current form can not be used for this: there are no simple way to connect to IPv6 network from behind multilevel stateful NAT (cheapest and the most common version of Internet access available). Yes, you can use, for example, stunnel to reach some kind of bastion host and use said bastion host to enable access to IPv6... but why will you do that? If you've connected your console or NAS with bastion host you can as well just connect directly to the bastion host without adding IPv6 to the mix!

and why would anyone ever willingly deploy an IPv6-only resource if the vast majority of users will not be able to reach it?

This is correct question - and the answer is simple: it's Ok if the resource is intrinsically designed to be only accessible by very limited number of users. I've shown some examples above, but you can invent many other similar uses. Some of them will not use IPv6 for that anyway (for example for a lot of organizations it's better to deploy their own VPN because it's more secure), but some of them may do. For it to be useful you need some simple way of obtaining connection to IPv6 network - and currently all simple ways assume that ISP will do that. And ISPs are the last persons to participate in such plan.

until something breaks this stalemate how will IPv6 gain any traction?

Poorly are we can see.
