The author of the article, Robert Miller, is a leading authority on MEV (Miner/Maximum Extractable Value). Those involved in MEV are quite a different bunch from most of the crypto crowd.

For one, they don't rely on "number go up" to make money, they use strategies similar to those used by HFT firms to make money from market inefficiencies. They generally don't have loyalty to a particular crypto platform, they just go wherever they can find a competitive advantage. They also tend to be much less politically outspoken and often left-leaning, in contrast to the vocal libertarian views that permeate the rest of the field.

They also most certainly aren't "imagining" making money. Most of their strategies are essentially elaborate forms of arbitrage, which are risk-free sources of profit by nature (until out-competed). Their only losses come from fees paid for deploying strategies that turn out to be unsuccessful. Even fees for failed transactions are pretty much a non-issue these days because of Flashbots.
