Argument: over time all bitcoin will be lost

hi all

Was talking about crypto with my sceptical buddy and I mentioned that of the 21m BTC that can ever be, some 3.7m are already lost, probably for ever, due to lost keys, words and drives.

He retorted, so eventually all bitcoin will be lost, it's a one way trapdoor. He means that there will be a tendency, over time, for bitcoin to be lost, the more time the more bitcoin.

I didn't have a response. It's an absolute finite resource that will, especially with 20 years of "first time wallet creator errors" to come, get inexorably smaller.

What are the thoughts of the sub.
