So if you argue against off chain mixing, you fail to note that your on chain depends on your off chain IP obfuscation, so your entire thesis of defense collapses in a house of cards.
The two are complementary.
Logic fail.
Long ago you and I discussed in public that linking together transactions if your IP conveys your identity thus breaks down the anonymity of rings. That was when you guys decided to add I2P because I informed you about that problem.
