Ringtones cost $2.40 because the cellular carrier takes 50%, as do other middlemen. If it were a direct market, a much smaller micropayment would work. There is no reason good micropayments, such as http://twitpay.me http://twitpay.me and http://rt2buy.com/ http://rt2buy.com/ (no affiliation) can't work in all the markets he dismisses, other than Amazon and Paypal costing too much to effect the transfer. But the cost is coming down, Amazon payments way undercut Paypal for small transactions. Its only a matter of time.
