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.
The issue IS dust: until it is not fixed it is pointless to make a bigger dustbin. And letting the fees rise is the only fix existing.
BTW: why asking just to double 350,000 TX/day? There is enough reasons and ways to fill of spam ten times more.
