If you think the world has enough Bitcoin users as things stand today, you have a point. If you think that use of Bitcoin growing by a factor of more than several dozen percent is desirable, then your point is ridiculous.
What makes you believe that users would feel the urgent need to spend their btc in dust amounts for b/s on a daily basis?
And even if they did, why would that be so good? To look cool waiting half an hour to pay a frappuccino? And at what cost?
For the umpteenth time - the issue is NOT dust transactions. The issue is that, with max block size capped at 1MB, the system is simply incapable of handling more than ~350,000 transactions a day - no matter the value of those transactions. Quit changing the topic. Quit putting words in my mouth. Such is dishonest.
