Erik, 

Fees AKA costs are the best spam control system and I thank you for
highlighting that. 

However, I think that bitcoin has yet to receive sufficient payments
usage to challenge credit card payments system when it comes to a race
to the bottom in terms of processing transactional fees. 

In the USA, where I am, large businesses like UBER, Lyft, and many major
telecom, cable, & electric utilities process huge volumes of regular and
irregular credit card payments on a monthly basis. Almost none oft hose
transactions are completed in bitcoin. 

A focus on lowering fees by increasing the block size by 10x is the
simplest method to start accepting more payments in bitcoin from larger
businesses.
