Tracking scammers

Hi, I have a potential idea to track scammers. However it is probably contentious. If the IP address of the computer that sent a transaction to the mempool were to be appended to the transaction, would this allow for scammers to be tracked?

As an aside, I can definitely see how this would be contentious. Everyone from people who are just privacy concious to the people who scoff at the irs would hate this. And if people were to escalate by using vpns, the natural counter of using blacklists that prevent vpn addresses of known vpns from publishing to the eth blockchain creates a situation where someone could add addresses of people they dislike (like hackers or the north korean govt) to the blockchain to block access, and then it becomes a cat and mouse game of moving money by juggling ip addresses.

But back to the basic premise. Would this assist in stopping the rampant theft occuring on the ethereum blockchain? Could the essence of this idea have safeguards added to it that cut out the potential bad part (along with the ensuing arms race) and still retain the core idea?

For example, what if the majority of eth stakers had to agree to an unmasking of the IP address, and the ip address were protected behind encryption that could only be broken through mass consensus? This would prevent the power from falling into wrong hands, and ensure its only used by people who have the approval of the entire community to see that specific transaction IP address.

Would this add benefit long term to eth, or are the potential tradeoffs to much?
