It seems like it would cost about $10/month to set up a public IP address through a service like NordVPN. You would take a bit of a latency hit, but presumably on the order of milliseconds.
If you're serving something latency sensitive, you can run your server in the cloud closer to the trunk of the internet, or you can pay SpaceX $100 month to shave off the latency.
It seems like SpaceX probably doesn't want people running servers on the starlink network for no good reason. So, their pricing doesn't seem like market inefficiency to me. It just seems like them charging a fair price for their service.
Hopefully they get IPv6 working soon? Then you'll at least be able to route your own personal stuff without NAT punch-through.
