This has been proposed before a= nd isn=E2=80=99t bitcoin but some alt coin. Taking people=E2=80=99s bitcoin= s after a certain period of time isn=E2=80=99t ethical.  Not to mentio= n it breaks some protocols such as proof of burn etc. If the past discussio= ns are any guide it is (thankfully) a nonstarter. 

Have a good one! =F0=9F=98=80

=EF=BB=BFDear Bitcoin developers,
I would like to propose a new BIP titled "Proof-of-Activity Reclamation (P= oAR)," which aims to address the long-term economic effects of lost and aba= ndoned UTXOs.

This proposal introduces a fully automated and rule-ba= sed mechanism to gradually recycle coins that have been provably inactive f= or over 20 years. These coins are returned to the undistributed pool and sl= owly reintroduced via future block rewards=E2=80=94extending miner incentiv= es while respecting the 21 million BTC cap.

You can view the full pr= oposal here:

I welcome your thoughts, suggestions, and critiques.
Best regards,
