Ha, yup! That's one way to look at it. Lost Bitcoins do essentially increase the value of the remaining ones in circulation.
It's a bit like accidentally dropping a gold coin into the ocean. Sure, you're out of luck, but there's now slightly less gold available for everyone else - making each remaining piece just that tiny bit more valuable.
So if you ever lose your Bitcoin keys (not that I'm recommending it!), consider it your unintentional gift to the rest of the Bitcoin community 😄⚡️💰
