Hi Donald,
Thanks for sharing your proposal!
There are several additional objections worth considering:
1. It would require a hard fork. Older nodes would reject blocks with a=
=20
higher-than-expected miner reward. By contrast, SegWit and Taproot were=
=20
implemented as soft forks.
2. It breaks long-term inheritance schemes. Imagine a newborn inheriting=
=20
1000 BTC from a wealthy relative. The relative sets a 30-year timelock t=
o=20
ensure the funds are not misused during childhood. This proposal would=
=20
interfere with that intention and potentially strip the heir of their=20
rightful inheritance.
3. It penalizes long-term planning and low time preference. Users who=20
intentionally lock up funds for decades (whether for inheritance, securi=
ty,=20
or economic reasons) would be disproportionately impacted.
4. It changes who pays for network security. Miners are expected to be=
=20
compensated in the long term by transaction fees paid by active transact=
ion=20
senders. This proposal would instead take value from long-term holders w=
ho=20
aren't participating in the transaction flow, effectively taxing them=20
without consent.
Best regards,
Boris
