A good ISP that supports IPv6 will give you a /64 range. That’s a huge number of IPs, 2^64. Easily enough for every device on your network to have a lot of public IPs. If you use Docker or VMs, you could give each one a public IPv6 address.
When every device on your network can have a public IP, there’s no longer a reason to have private IPs. Instead, you’d use firewall rules for internal-only stuff (ie allow access only if the source IP is in your IPv6 range).
This is how the internet used to work in the old days - universities would have a large IP range, and every computer on campus would have a public IP.
Of course, you’d still have a firewall on your router (and probably on your computers too) that blocks incoming connections for things you don’t want to expose publicly.
wouldn’t /64 still leave you with 64 bits for you to do whatever? Ipv6 has a 128 bit address. If you can do subnets with a small usable portion of 32 bits, then you certainly can with a full 64 bits
How does that work, having the same IP internally and externally?

A good isp would give you something bigger than a /64 - /56 or /48. something that you can subnet.
