Who says anything about a broken incentive model. You've made past
claims about resource requirements that I think made no sense and then
failed to defend them when they were challenge.

With suitable software improvements running a full node could be done
in as little as a few gigabytes in disk space (e.g. cost 25-50 cents),
and as 50-100kbit/sec bandwidth in and out ongoing, and a moderate
amount of ram. Power costs are already just a few cents per month.  By
far the greatest cost is the figuring out and setting up part, which
bundling could fix. The exact resources could be tunable to what the
users are willing and able to contribute.

If improved marginal security and privacy in addition to supporting
the network is not enough incentive to overcome costs like these then
Bitcoin is already doomed.  I think that fundamental costs aren't an
issue at all, just implementation warts and education are.

Part of asking the question is feeling out which improvements need to
happen first, and what the prospects of getting the bundling going
once those improvements are made.
