Why doesn’t every computer have a hardware based static ipv32 address, along with a private key to prove it is the sole owner of the address?

IP address is really the best comparison here. Some computers share an IP just like entire call centers may share the same phone number. And neither IP addresses and packets nor phone numbers are properly authenticated without additional enforcement systems.
Internal networks exist for computers and phones. It’s a nice parallel.
No, computers can’t share IPs
They can share the same router and therefore have the same public IP.
Yes, but no. The public IP is that of the router, which NATs packets to each host, each of which must have a unique private IP. The public IP does not reference or identity hosts behind the router.
A phone number does not uniquely identify a phone either.
Sure they can. If you put a network behind a router they will share an egress/ingress IP. And there are certain high availability setups where computers share IPs in the same subnet for hot/standby failover.
Yes, but no. The public IP is that of the router, which NATs packets to each host, each of which must have a unique private IP. The public IP does not reference or identity hosts behind the router. And that’s not how HA works. Only one host is assigned the active IP at one time.
When you do call routing with a PBX each phone has an unique extension, equivalent to the private IP of each host.
Oh, and there’s also anycast, which is literally multiple active devices sharing an IP.
You’d have to know more about BGP to know any cast doesn’t function as you think it does
Ah, I see we are resorting to ad hominem attacks now.
lol ok sally
So computers can share IP’s then right? By your example they are sharing their public IP. From the perspective of the server you are connecting to, all the machines on your LAN have the same IP. Same way multiple physical phones can be connected to a single landline, all those phones share the same number.
No, not the same
