Do you think lost Bitcoin will be a real problem?

Hi everyone, I propose a little discussion.

Do you think lost Bitcoin will be a real problem?

People at the beginning of Bitcoin did not necessarily pay attention so we can consider that several million Bitcoins have been lost. Do you think it will be a real problem in the future given the limit of 21 million, would there be solutions or maybe it’s not a problem so no need for a solution.

I don’t know how it could be set up, but I had thought of something, it would be to put a duration of 20 years for each UTXO, that is to say that if the funds are not moved, after 20 years, it would be redistributed to minors.
