Digital goods are inherently more difficult to sell because it is so cheap to copy and distribute them. "Information wants to be free" has a kernel of truth in it; "free" is the most natural state for information. It can be copied easy, quickly, and cheaply.
DRM technologies feel draconian, but probably only because they restrict legitimate fair-use in addition to protecting information from unauthorized distribution. Ultimately, I think more DRM is going to be necessary to protect IP. Fairly soon, all IP is probably going to be distributed online (books, music, movies, etc). If piracy isn't kept to a minimum, it will eventually cannibalize the IP market.
