Other people are a lot nicer than I would have been with adjectives like delusional. I would have said flat out stupid.

Let's say your non-existent fictional company is as good as you say. Why wouldn't YC want it? If you're knocking out a portfolio company they'd want to hedge and have the competitors growth to even out any potential losses. Diversification and unicorns are the entire VC model.

Now let's come back to reality and admit that you've got absolutely nothing-- and promising companies with millions in revenue who have raised literally billions of dollars still go extinct all the time.

The problem with people who aren't experienced in startup spaces is that they always over value their own ideas. They think they're first when they aren't...or they truly are first because there are systemic, model, or market features that make that space unappealing or at least much more difficult to innovate in than outsiders expected. From your details, you are an outsider--you don't even fully understand the core technical pieces.
