That's a fair point. Speaking only for myself, I think I fail to understand why it's important to situate philosophical discussions in the context of all the previous philosophers who have expressed related ideas, rather than simply discussing the ideas in isolation.
I remember as a child coming to the same "if reality is a deception, at least I must exist to be deceived" conclusion that Descartes did, well before I had heard of Descartes. (I don't think this makes me special, it's just a natural conclusion anyone will reach if they ponder the subject). I think it's harmless for me to discuss that idea in public without someone saying "you need to read Descartes before you can talk about this".
I also find my personal ethics are stronly aligned with what Kant espoused. But most people I talk to are not academic philosophers and have not read Kant, so when I want to explain my morals, I am better off explaining the ideas themselves than talking about Kant, which would be a distraction anyway because I didn't learn them from Kant, we just arrived at the same conclusions. If I'm talking with a philosopher I can just say "I'm a Kantian" as shorthand, but that's really just jargon for people who already know what I'm talking about.
I also think that while it would be unusual for someone to (for example) write a guide to understanding relativity without once mentioning Einstein, it also wouldn't be a fundamental flaw.
(But I agree there's no certainly excuse for someone asserting that they're right because they're rational!)
