As for the incremental scaling . There's been 13 years since the launch . 6 years since blocksize wars . I remember Adam Back , Lopp and others saying at that time it was ok to increase it . Right now , according to what most devs believed , blocksize should be at least 32 MB . How big do you think blocksize should be currently ?
if you increase block sizes so more transactions can fit in each block then that would help bitcoin scale. but if you allow a single transaction to hog up all the blockspace that's not helping anything.
so if you could increase the blocksize to say 32MB and require each transaction to be less than say 1KB then that's progress. There's no way bitcoin can get world domination without blocksize increasing. Unless people are satisfied with using something like Lightning Network but I don't think some people want to use that.
even with the above restrictions people could still use bitcoin for ordinals and stuff. so it might not really change that aspect of things. it just might mean more of the same.
