Is a storage fee averaged out over many future blocks - but not hardcoded v=
alue and regulated by a free market?


The problem with demurrage I see is that the fee is taken when you spend. T=
here is no additional income for miners if people are still hoarding.
In tail emission even if people are still hoarding - the fee is taken immed=
iately and is distributed to miners.

We have a hope there is still the global adoption ahead (most of countries =
are like El Salvador). It may increase price and marketcap of Bitcoin by or=
der of magnitude.
And that's why hoarding in demurrage may still exist: due to extremely appe=
aling long-term risk/reward (i.e. relatively small, delayed tax versus huge=
 possible profit)

First of all - while I suspct you already understand this issue - I should
point out the following:

The immediate danger we have with halvings is that in a competitive market,
profit margins tend towards marginal costs - the cost to produce an additio=
nal
unit of production - rather than total costs - the cost necessary to recover
prior and future expenses. Since the halving is a sudden shock to the syste=
m,
under the right conditions we could have a significant amount of hashing po=
wer
just barely able to afford to hash prior to the halving, resulting in all t=
hat
hashing power immediately having to shut down and fees increasing dramatica=
lly,
and likely, chaotically.  Your proposal does not address that problem as it=
 can
only measure difficulty prior to the halving point.


Other than that problem, I agree that this proposal would, at least in theo=
ry,
be a positive improvement on the status quo. But it is a hard fork and I do=
n't
think there is much hope for such hard forks to be implemented. I believe t=
hat
a demmurrage soft-fork, implemented via a storage fee averaged out over many
future blocks, has a much more plausible route towards implementation.
