Care to give me a single example of high cost luxury open code?
The 'if you charge a cunting fortune, they will come' theory is a prime example of the laughable unworldliness of some of the folks involved in Bitcoin.
I'm sure they'll enjoy charging the equivalent of $50 to send a few cents to each other. The rest of the world will carry on happily as before or go with a system that's designed to actually accommodate them.
"The rest of the world" is irrelevant as they don't control the resources ie. they're poor.
Those that do are not interested in using it for sending cents and are not deterred by transactions costs.
