We can debate this until we grow very old, but the point is this. The can can only be kicked down the road, until the road ends. At some time in the future, once everything have been tried to bypass the block size problem, it will have to be increased. Only time will tell, when this situation will be forced and not asked for by the people. ^smile^

The road will end soon, LN and side-chains will not be the ultimate solution.
