Segwit is more like 1.3MB equiv, to 1.75MB equiv in a rosy scenario. It also gives a heavy discount to signature heavy transactions like the vaporous LN. Most importantly, the "soft" fork method allows no room for protest at the node level.
It has the added "benefit" of leaving all non segwit nodes in a half broken state, not able to fully validate. All done without their request or permission.
way to understate segwit.
1.75x incess is HUGE!
scaling bitcoin isnt about how big we can make the blocks, but how efficiently we can use block space
At the end of the day you can only put so much data in a 1MB space. When all options are exhausted the only path forward is to increase the blocksize. So truthfully, scaling bitcoin is about BOTH "how big we can make the blocks" and "how efficiently we can use the block space."
