I'm just your "average Joe", and me and all of my average Joe friends, and all of the rest of the average Joe's out there are not going to use bitcoin if it takes more than ten minutes for a transaction and high fees will soon price alot of people out. Those are the cold hard facts. You can kiss the fabled "mainstream adoption" goodbye.
I tend to agree with this logic. The development of an ever increasing fee market due to the block size constraint is the first time I've ever really been concerned for Bitcoin. It was originally developed as a peer to peer digital currency but that is slowly being changed. I'm not sure why individuals suddenly believe it should just be a settlement network. I'm not overly happy with core's current roadmap, if something isn't done Bitcoin will lose a lot of the qualities that made it so unique and exciting.
