Right, that would make sense until you realise in both cases (lightning and sidechains) these technologies need bigger blocks to scale.
But before they need to scale, they just might need some help convincing potential users they are even necessary at all.
I think it is obvious that:
a) without new technologies we will need 24 GB blocks. ( 10 billion transactions per/day )
b) current technology cannot handle 24 GB blocks (and will not handle any time soon)
c) with SC and LN bitcoin can stay decentralized and handle billions of TPS using small blocks (maybe bigger than 1MB be we are far from reaching limits of 1 MB blocks)
it great that you think something is obvious.
If you'd like your thoughts to have any kind of value at all, why not show some work for b and c?
Bring some evidence to the table instead of just your feels.
