Even if it's backed up, will those backups be retained for 4 years? 8 years? By the time someone is in power will they even be able to restore this content? Probably not.
We're left with things like Wikipedia and archive.org snapshots - second hand resources that can easily go away.
The brain drain is real and fucking terrifying.
Not really, but I can give you my reasons for doing so. Know that you'll need some shared storage (NFS, CIFS, etc) to take full advantage of the cluster.
- Zero downtime for patching. Taking systems offline to update Proxmox sucks, especially if the upgrade fails for some reason. A cluster means I can evacuate one host, upgrade it, and move on to the next with no downtime for the hosted VMs.
- Critical service resiliency. I have a couple of critical systems in my home lab that, if they unexpectedly go down, will make for a very bad day. For instance, my entire home network (and lab) is configured to use a PowerDNS cluster for DNS. I can put the master PowerDNS server on one host and the slave on a second host - if I have a hardware failure, I won't lose DNS. I have a similar setup for my Kubernetes cluster's worker nodes.
- Experimentation. A cluster gives me a larger shared pool of CPU/Memory than my single host could offer. This means I can spin up new VMs, LXC containers, etc and just play with new software and services. Heck that's how I got started with my Kubernetes cluster - I had some spare capacity so I found a blog post that talked about Kubes on LXC containers and I spun it up.
I hope that helps give some reasons for doing a cluster, and apologies for not replying immediately. I'm happy to share more about my homelab/answer other questions about my setup.

I filed mine mostly because I knew I was going to be getting a refund. I wanted to make sure that I got that money before the IRS was completely fucked. This may be the last year that I purposely overestimate my tax burden (e.g. paying more in taxes than I ideally should).
In the past, people would say that you're giving the government an interest-free loan - I didn't really care about that because I knew I would get that money back later. Now? I'm not so sure.
