Clarify which dictatorship you want. Because if it's not dictatorship of me over only my mempool and nobody else's, then as a matter of fact I am not running your idea of Bitcoin. I have control over my node. I have a mind and I use it to tailor my settings. What you want is a dictatorship of developers, ironically, just your preferred flavor of it.

You have control over your node but not over what valid transactions are included in the blocks, except if you work and mine them by yourself. Mempools can be full of various transactions but only transactions that pay enough fee to be included in block are relevant in the end. I want developers to not dictate anything about transaction types. Bitcoin transaction is a digital message and I want everybody to be free to sign any kind of message they want as a transaction even if I and 99% of other users consider it spam/waste. We know that free market is the only way to filter transactions without dictatorship and I would like to have as many people as possible to understand that so we can continue with more productive discussions like Bitcoin privacy and censorship resistance.
