That just becomes a market design question. There's been some trivial
effort put into that for bitcoin (ie, getting people to actually chooses
fees based on the weight of their transaction, and having weight be the
sole limiting factor for miners), but not a lot, and there's evidence
both from previous times in Bitcoin's history and from altcoin's that
the market can support higher fees.
Should we work on that today, though? It doesn't seem smart to me:
the subsidy is already quite substantial ($6.5 billion USD per year at
current prices) so raising fees to 10% of block reward would transfer
another $650M USD from bitcoin users to miners (or ASIC manfucturers
and electricity producers) each year, achieving what? Refuting some FUD?
Cheers,
