Why should I spend the time and energy to deal with IPv6 when disabling it fix many issues ? The listed advantages are not worth the troubles in my experience.

Would have been great if the post quantified the advantages. For networks (order of preference): IPv6 only > IPv4 Only > Dual Stack.

It's not so much that the advantages of IPv6 are all that compelling. Rather, it's more that the mechanisms put in place to deal with a nearly-exhausted IPv4 pool (NAT, and CGNAT in particular, etc.) are not great, and any opportunity to negate the need for them ought to be pursued.

  But you still need these mechanisms for the time being. And personally, I do like NAT. I'm not a fan of exposing my internal networks to the internet. Having everything hidden behind a single address is neat.

    As has been discussed ad nauseam, getting rid of NAT does not mean all your hosts are exposed. You would still have a firewall, and managing that firewall is much more straightforward when one doesn’t have to deal with address or port translations.

      But my internal network structure will still be exposed.

I've run dual stack at home and at work for years and have had no issues. You might have issues if you have really old junk that's just broken.

  My current internet provider doesn't support IPv6 so I'm good. I noticed that removing the AAAA records in the DNS configurations of my domains magically fixed a lot of weird network issues reported by the users.

Increased number of available IP addresses, improved security features, simplified network management, reduced network complexity, and support for new technologies. The adoption of IPv6 will lead to cost savings, improved network performance, and increased scalability. Scalability may not matter in the typical home network, but in an enterprise environment, the cost of up-keeping the network backbone is significant.

  >simplified network management I keep hearing this, but it doesn’t seem more simple to me. My ISP won’t reserve me a /48, so I can’t control the management ips of devices on my network. The solution is apparently to set up dynamic dns, which I have no interest in doing.

    Just split that /64 into smaller /80 subnets. If I were your ISP, I would be upset too. The apparent issue here is that you're falling back to what's familiar- static IP addressing. How about mDNS?

      You can't use a smaller subnet than /64 for devices that use SLAAC for address allocation. (Unless you're putting them behind an IPv6 NAT, so thry can have their oen private /64).

        Or setting up things like stateful DHCPv6: https://serverfault.com/a/714923 https://serverfault.com/a/714923 It's not great, but it's an option!

      I guess what I meant is that my ISP won’t hand out a stable IPv6 allocation. Ie, my entire address range changes weekly.

The advantage mostly falls to the infrastructure. In theory it performs better, but only marginally, which is quickly overwhelmed by simple issues like inferior routes. As an end user, frankly I stopped caring long ago.
