>As for comparison payment processing space, this is more in point 1. Bitcoin is not cheaper. Bitcoin is extremely expensive to use and intended to be expensive.

Bitcoin is currently overly secure, due to the block subsidy, so therefore total mining costs relative to number of transactions is very high. As the block subsidy diminishes, this ratio will decline

Total security can be maintained, without transaction fees increasing, if transaction volumes increase, which is entirely possible, and is what has historically happened.
