Exactly -- both block size proponents and block size change conservatives seem to be glossing over this aspect - much to my dismay.

Choosing the size limit is choosing the size of a scarce resource.  By fiat.

It is wrong to think that a "technical consensus" can choose what is best here.

The block size limit defines the scope of a resource for which all fee market actors bid.  That, in turn, defines who is in the fee market and how they behave, what market choices are made.

It doesn't matter how or why the limit was originally enacted, what Satoshi meant to do.  What matters, economically, is what is.  What the software and our $3B economy & market knows and sees today.  (I think some block size change proponents miss this!)

The solution lies in transitioning this size limit to the free market.  In the end, the users must choose their desired level of growth, decentralization, etc.  We cannot rely on some dev's idea of the proper level of fee, proper level of growth, proper level of decentralization.

And IMO, a "floating limit with training wheels" is better and stronger for bitcoin's health from a governance, user choice and free market perspective than simply "hard fork to 2MB, come back again in 6 months."

Exactly right. Bitcoin does not have a free market for fee though, and
literally all the discussion so far has neglected some fundamental
aspect of this, as you described. It's not at all a "technical" or
"engineering" decision. It's the question of how to potentially
re-design a fundamental part of Bitcoin, and the proposals so far
don't address this. What is the price of the scarce resource of the
blockchain and the mechanism to decide on price, once the subsidy runs
out?
