what would the incentive for a pool map npubs to IP addresses or ranges once they’ve already gotten the block reward?
Also why should they wish to use bandwidth on serving clients while they instead could receive transactions and possibly find a block?
The miners should only be hashing away and securing the network.
Currently there is no incentive for pools to do this, because everyone is using ICANN domains and IANA IP addresses.
Currently there is also no incentive for me to mine at home, because I would make a loss. However, I would love to mine at a loss with my RaspiBlitz if an upstream pool or proxy were to take on the role of IANA by giving me an IP address. Sure this would initially be an IP address in a local network, but why not do the same on a global level if it proves to be useful locally.
Pools that compete with IANA could serve a market of miners who care about removing the authority from their addressing system more than they care about profitability.
Regarding domains: ICANN just manages a fiat list of who owns what namespace. We don't need them because we can create our own namespace (npubs) managed by entropy rather than fiat.
With the Bitaxe and StratumV2, ideological miners bring an interesting twist to security.
You can mine at a loss to enforce your mempool policy if you don't like ordinals.
IANA is just another reason to mine at a loss - which is probably good for decentralization...
