i know this message will get deleted but heck..

miners costs do not increase with blocksize.
asics do not see, store or validate transactions. they are only given a hash.
this hash is the same length whether a block is 50kb or 50mb
pools dont validate transactions in 0.1 second before making a block template. they have already received validated and put into mempool the awaiting tx's minutes prior

as for the user node post block solution validation. again most nodes also already have then transactions validated in mempool before the block is even solved. so getting a compact block and linking the txindex to the transactions in mempool is not hard work. maybe a few transactions are missed and need to be requested, but over all. the validation time of a 4mb block in 2021 is not more than a 1mb in 2015

now back to the fee/blocksize details
if there is more space. then a pool will get more fee's
even a 1sat/byte is at a 1mb= 1,000,000sat minimum
all a pool has to do is accept transactions with 10sat if it wants 10,000,000 sat or 40sat/byte to get 0.4btc

but where if there were the true open utility of actual 4mb space(not the cludgy code). a pool only needs to seek 10sat/byte to get a total of 0.4btc

and if it were to want 40sat/byte they would get 1.6btc for 4mb space

so yes fee's will be cheaper per transaction.. but the total the pool gets will be more

its simple math
1sat/byte at 1mb=1,000,000sat for the pool
1sat/byte at 4mb=4,000,000sat for the pool

10sat/byte at 1mb=10,000,000sat for the pool
10sat/byte at 4mb=40,000,000sat for the pool

and please can most of you in this developer discussion stop with the propaganda that it will cause centralisation..
sorry but offramping users away from being active users of the bitcoin blockchain, to instead use other networks of convenience is what will cause more centralisation of nodes onchain.
because if people dont use/touch/interact with bitcoins blockchain regular. they wont want/need to full node it regular(common sense)
