The article seems to be down for me. But I'm curious if there would be any mechanism in place to limit used sales in any way since electronic copies do not suffer from the same problems of wear and tear etc that a physical book would. If I can buy a used copy of a digital book cheaper then there is really no reason ever to buy a new copy. Hell , if the market is convenient and has enough liquidity then what's to stop me from buying a book, reading a chapter and then selling it and buying the same book back again at a reduced price when I want to read the second chapter? I could see this might cause the price for ebooks to crash towards 0 unless there is something in place to rate limit purchases/sales.
