Property is not the same in cyberspace. Privacy is not the same. Sovereignty is not the same. Indeed, very little is the same. It almost sounds like heresy to talk about regulation of the Internet, but, of course, there is a structure to it, there are protocols and regulations governing it.
Regulation is both necessary and inevitable.
Because this form of regulation is often invisible to most users of the technology it is particularly insidious and poses a great threat. Each of these can influence the others as well. Of greatest interest to Lessig are law and architecture. More significant are filtering mechanisms that can restrict access to sites. While these may seem desirable to allow parents, for example, to prevent their children from gaining access to disagreeable sites they could theoretically also be installed at higher levels of the computer chain, blocking access of certain sites for a large number of users.
