this is basically forcing people to move their coins. maybe i like to buy 1 bitcoin and hold it for my retirement and i don't care what happens during that time.
Yes I agree, that is the downside of this suggestion. However, this seems acceptable to me. How much effort is it really, to broadcast a simple transaction every 2 year? It could alternatively be 5 year, or 10, and with slower erosion factor, whatever seems acceptable to 95% of users. Any erosion will increase transparency and security, it will just take longer to start and be less effective. Still an improvement from what we have now.
you have not touched your pension pot in 3 years so its time you start handing it out..
Yes maybe I should have been clearer about this here: the count will only begin after the soft-fork takes effect, so all users will have a good few years to hear about this change in consensus (I did write it in the link I posted btw). Haven't thought about people that have already intentionally locked their private keys away for many years without them being able to access them at all. It that a thing?
Just want to clarify once again, the point is not that people should hand out money after some time, only to redistribute funds that are actually lost.
