I would love to see more people interested in discussing this. Social
wrangling is certainly the best we have, but is it the best we can do?
Certainly a certain amount of discussion and back and forth is necessary to
come to consensus, but it would be nice to have a discussion and come to a
consensus on things like the minimum things required to decided consensus
is for something (the absence of which makes it obvious that consensus is
currently against), and the maximum amount of things required after which
it would be clear and obvious that consensus for something has been
achieved.

I'm curious to know why you think this is the case. If you mean that
centralization of custody is a problem for this, I very much agree.
However, I don't see how having wallet votes would incentivize
centralization of custody. Rather the opposite actually - one more reason
to self-custody.

Regardless, I wouldn't suggest having wallet *votes* per se. I would doubt
we'd get a high enough response rate on that to really determine what
broader consensus of coin-owners is. However, if we had coin-weighted
polling, it would I think be a very useful signal by which we could
determine something (to some degree of uncertainty) about what consensus is
among that group (of coin owners who take the poll).

Theoretically, the economic majority of bitcoin holders can direct the
majority of mining power, and can control where the current chain goes (of
course not discounting the ability of the economic minority to hard fork
away if they want, taking a proportional minority amount of mining power
with them).

One could also think of it like Polybius's three part government, where the
parts in bitcoin would be: developers, miners, and holders. Perhaps a
consensus among all of them should be ideally sought after for a smooth
upgrade. Because of the blocksize wars, many think miners should simply act
as a machine to implement the will of the bitcoiners. However, I think
people sometimes forget that miners are also bitcoiners and they have a
unique and important perspective. If the opinions and interests of miners
is already adequately considered as part of our chaotic discussions on what
consensus is, then great. If not, it would seem that the miner signaling
process is a reasonable place for miners to decide to delay and force more
discussion. While its unlikely the average user knows much about the
technical aspects of consensus changes, the fact is that there are many
non-developer stakeholders, and it would I think be a very beneficial
achievement to figure out a way to incorporate those stakeholders into the
process of determining consensus on the most important changes to bitcoin:
consensus changes.
