[Bitcoin-development] Block Size Increase

Yes - but you must recognize that is precisely 50% of the picture.

Others have made different assumptions - taking the [1MB-constrained]
market *as it exists today*, rather than in some projected future.

Raising the block size limit then becomes a *human decision* to favor some
users over others, a *human decision* to prevent an active and competitive
free fee market developing at 1MB, a *human decision* to keep transaction
fees low to incentivize bitcoin adoption, a *human decision* to value
adoption over decentralization.

These statements are not value judgements - not saying you are wrong -
these are observations of some rather huge, relevant blind spots in this
