I still frozen coins will get confiscated and reused/
Maybe after 50 years of an address not having a coin moved out of it, it gets forfeited and pushed back into rewards.
This goes against the philosophy of Bitcoin. Forfeiture of assets shouldn't be an option even if it has never been touched or stayed dormant for the past century. There is also a problem with an arbitrary threshold where there isn't a good way to determine how long the coin should stay dormant before being recirculated. This would pose far too much of an issue in terms of both implementation and motivation. Even if you start to recycle OP_Return outputs, the purpose of sending them by the original owner would be defeated.
Between this and implementing a tail emission of sorts, I'd support tail emission. There shouldn't be a scenario where an asset gets confiscated because it lays dormant.
but the precedents in finance exist..
so if 2059 comes along and 300,000k coins from 2009 blocks never moved and you reset them back.
you do not increase the actual 21 million coins.
if the announcement is made in 2049 that the recirculating of the frozen 2009 coins begins in 2059 the problem is solved if almost none of the frozen coins get moved.
It does have the problem that maybe of the 300,000 frozen 2009 coins only 50,000 are really frozen.
but the owners of those unfrozen coins can simply move them to a new address.
no loss of privacy And eventually the 21 million coins all get mined but with a longer delay say 2300 not 2100.
I guess tail emissions are better as they would be a longer solution.
but reclaiming frozen coins would work for at least as extra 50-125 years
