The inability to clear dust on Bitcoin is a serious problem. It's fragmentation, for your money, that makes it impossible to spend (given the current fee structure, which has been defined as "normal" now that Bitcoin is "digital gold" rather than a transmission network).

It's like every time you buy something, the change just disappears, and once a week you have to spend another $20 to sweep it up. This is not how currency is supposed to work, and it's been retconned as somehow being a good thing.

Don't hate on me for stating the obvious here. Whatever happened to the "no fees" that advocates like Marc Andreesen were promoting circa-2014?

(yeah, obviously false given the transaction fees paid to miners that have since become prominent when the blocks filled up)
