Not just mobile, home users too. And although some of us wanted IPv6 just like the Internet itself the vast majority of people just got it because it seemed like that's what everybody had. Which is fine.
When Sarah's mom's ISP rolls out IPv6 (or maybe when she gets new CPE because she upgraded service, moved home, or it just eventually died), her devices get IPv6, but she doesn't care, Facebook still works (it might be slightly faster, but not noticeably) and Sarah's mom doesn't know what the Internet Protocol Version Six is except that it sounds like something from a Star Trek convention.
Sarah's employer is Big Corp. When Big Corp's ISP rolls out IPv6, Big Corp IT agree that since not everybody went on the IPv6 training course yet, they should explicitly disable IPv6 to avoid unspecified "problems". Everything still works as before and Big Corp's IT department are cheerfully running stuff that actually matters in the Cloud, so what do they need more addresses for anyway? Maybe in 2025 there will be a budgetary requirement for IPv6 at Big Corp. Or maybe not. Perhaps the best chance for Big Corp to get IPv6 is if IT screws up and mistakenly doesn't disable it, then they find that later doing so makes things worse.
