Even if somehow that did not become a problem, there is the fact that Bitcoin is an inherently deflationary currency. This creates problems with hoarding (which we are already seeing), and makes it harder to repay loans (loans are crucial to a functioning economy, despite what those "occupy" protesters tell you).
I don't think I have ever seen or heard an "occupy" protester say that loans are inherently bad and I went to one for a couple of hours in Saturday. The main thrust of the "movement" is: 1. Tax the rich more - to make income and wealth distribution a little more equitable 2. Re-install Glass-Steagal and regulate the financial industry properly 3. Eliminate corporate personhood and institute campaign finance reform to make our democracy more healthy
