What's the problem with paying 10 bucks instead of 10 cents to securely transfer a million dollars?
A majority of the transactions are not 1 million. If you are suggesting a sliding scale where 95% of transactions are 4 cents a peice than that also doesn't pay to secure the network.
You are being way too optimistic if you believe bitcoin can survive alone on many large wires transferring large sums of BTC for 10 usd a pop.
And no , I will not pay 10 usd to transfer 1 million dollars between my wallets or for every large purchase. I would rather sell all my bitcoin and work supporting an alt that offered reasonable fees.
Convincing others that 10usd fee is an improvement is going to be very difficult as well as most people don't care about security or privacy, but about saving money. I'm sorry that bitcoin is growing to become more popular than you prefer but that was always the plan ... go big or fail .
