We still have people thinking that increasing the block size limit by a factor of 20 will increase the blockchain size by the same factor.
This is FALSE.
The blockchain will grow slowly over time. It could take us years before we reach this limit. Besides the cost per GB of storage is pretty low these days.
What would be very beneficial is including more options into the fork. If the fork happens, this could be our last one. Once we reach a few million users doing so will be almost impossible (it is hard already).
