These days, your ISP would (hopefully) give you at least a whole (static) /56, so you can always reserve some prefixes for your not-really-home networks ?

Most of the home networks I use are still behind a NAT use a single ipv6 to interface the world and within the network each computer has an internally assigned ipv4 just in case some operating system may not be compatible with ipv4.
Still are many old routers using ipv4 only out there as not many people care to renew their hardware as long as their WhatsApp and Netflix works.
they would first ban the selling of new devices not compatible with IPv6, then forbid ISPs to advertise IPv4-only connections as "Internet", then ban the selling of new IPv4-compatible devices.
(In a few years we're going to reach anyway the point when IPv6-only connections (mostly in Asia) outnumber IPv4-only devices (mostly in Africa, which sucks because they're the least able to afford an upgrade, but then being forced behind CGNAT sucks too).)
Now, IPv6 (when properly implemented, which is another failure mode) comes with much better safety out of the box (like not being able to scan all the suffixes in a reasonable amount of time to find computers on the local network to target), but I'm still impressed that now we seemingly have hundreds of millions of personal computers "directly" connected to the Internet with at best only the OS firewall as protection (when one exists), and it hasn't resulted in major hacking issues ! (yet.)
There never really was any such thing as a safe network, but it used to be acceptable to assume LAN traffic was safe. Now we know you might be on airport wifi or a large corporate network with compromised systems and the OS and systems software needs to handle that.
I guess the hackpocalypse will have to wait for when low-end computers (like those in tvs, cameras, personal assistants, connected doorbells, home automation, refrigerators) - you know, "Internet of Shit" that you can't really expect to feature its own firewall (?) finally get upgraded to IPv6 ? (How does it look like today ?)
It's a coin toss on if BT will properly allow ipv6 traffic each time the router reboots.
I've had to make provisions to force ipv4 on my machines because although composer et al. runs fine on my vps and elsewhere, if it tries to access it via ipv6 at home it more often than not hangs indefinitely.

Most people want ipv6 so they can get more ips / static ips, but from a legislation perspective its more about future proofing and staying relevant.
My statement was clearly the use case of ipv6 a direct answer to your question. Why? as in why would people want ipv6.
Anyway have fun playing dumb.
You forget about the opportunity cost that comes from our broken Internet where you cannot assume end-to-end network connectivity because you might have to deal with NAT and especially CGNAT ! (How many protocols end up overcomplicated (=expensive) and dead in the water because of that ?)
There's this goofy band of people that know just enough to bring their own router but don't understand why a misconfigured AAAA record can mess up the happy eyeballs algorithm and are convinced Comcast is "censoring" small business. It's funny and kind of sad to read comments from people who are certain their misconfigured networks are the result of some "international conspiracy" against them. That's probably why Comcast has it turned off on the routers they loan to customers.
You must not have met many ISPs.

I have the same network ISP for my apartment and they give me only IPv6.
I hate it.
Edit: Which I could do as my ISP and mobile network both support ip6. Y'all need better ISPs :D
If only there was one around here, but alas, they're all basically the same 2-3 ISPs - a couple of main ISPs, then smaller ones who are just using their network and renting bandwidth.
