That's the principle idea behind Bitcoin and without it, there is no reason for it to exist. So if that discourages some people from getting into bitcoin, that's a good thing.


Your idea is adding complications and is relying on other layers that are not part of the Bitcoin protocol itself which makes it not-work.

Additionally what you are dealing with is lacking uniqueness and reliable identifiability. For example in Bitcoin when you have a key, that key is unique and can not be produced by anybody else. Others cannot produce a signature from your key without having your key.
But when it comes to something like IP address, many users don't have a unique IP since their ISPs give them dynamic IP. Secondly unlike a private key, that IP address can be spoofed and a malicious actor can pretend to be someone else!
