These aren't show stopping problems. Web pages and browser extensions are pretty low barrier to entry. Exchanging cost is not too bad, but probably the biggest hurdle still. Privacy I don't think is a problem here. One random address to another is good enough for these type of transactions. Pegging to another currency means centralization, though that is acceptable to plenty of people. You said you wished there was a solution, all I'm saying is there is a clear path to how it could be done.
