right now 1mb has a yearly potential of 52gb.. its been long enough now and we are at no where near 52gb for the total of 6 years. so i see very little reason to increase the blocksize right now.. if anything we should be coaxing the pools to stop delaying adding transactions and to actually start filling all blocks with tx's as they happen..
I must be reading or comprehending this wrong because you should know way better than thinking because of bitcoins transaction past has anything to do with our current block dilemma and that we should be proactive.
