[Bitcoin-development] Long-term mining incentives

I think the basic reality is that a) an arbitrarily elevated level of
hashing is fundamental to a truly decentralised, autonomous network,
and is an essential cost to maintaining Bitcoin, b) there are no signs
that this fact will change, c) there must be some replacement to the
current system of incentivisation through debasement (inflation).
Arguments about limiting block size versus setting minimum fees are
confused because ultimately both mechanisms should ideally achieve the
same outcome: a market price for transactions which means that a) not
everyone who would make a TX if TXs were unpriced does so (reduced
number of TXs) and b) the market price is used to fund hashing. This
is just the nature of prices, it always reduces effective demand, but
without prices supply must collapse and the market must fail.
Regardless, if every time the network gets close to reaching the block
size limit the development community gets scared and raises the limit,
then such a limit will never be an effective tool for setting a market
price. Personally I think trying to artificially limit supply to
create a price for transactions is a needlessly complicated way of
trying to achieve this goal. I think minimum fees for transactions is
a better, simpler option.
I would go a step further and say that the development community will
struggle forever if it tries to play the role of the centralised
economic planner in setting prices for network services. The community
should look at more dynamic ways to let network users express their
preferences for security and their willingness to pay for it. I've
written on the issue -
As far as the argument that fees will drive people away from Bitcoin,
I can't believe that. Everything we desire has to be paid for somehow.
People will accept a fee for making Bitcoin transactions if Bitcoin as
a result is a stable, useful service. Bitcoin as both a currency and
as a transaction network has strong network effects, so, ignoring
sidechains, it's highly unrealistic that a mandatory fee will drive
people away from Bitcoin when the alternatives are dubious knock-offs
with no network effect, and fiat, which is even worse in regards to
the hidden and malignant costs it exacts.
