So what are the OTHER safe & reliable methods of "addressing scalability issue" without increasing the block size ?
Obviously. Read through this topic carefully, instead of just barking around like a rabid chihuahua, and you will find at least a few good ideas.
But they won't get a chance to really develop and built the infrastructure, as long as the transactions are free. So forcing transactions to stay free is probably the best strategy to kill these so needed innovations; and I am old enough to suspect that it might not be a coincidence, but an agenda at work.
