Here, I'll address them: - Miners will make less revenue is speculation. (see: barefoot mining revenue after implementing DATUM blocks) - Peter Todd himself made private mempool propagation with his Libra relay so he is, by his own estimation, hurting small miners on purpose. - Fee estimation is pseudoscience (just because I don't know how much some guy in China pays for his hamburger doesn't mean I don't know what I'm willing to pay for my hamburger.)
