Pure Direct democracy implies, in practice, that citizens are constantly involved with politics, making decisions on topics, from trivial to critical, they cannot possibly be always familiar or expert on. While every citizen has ultimately the right to judge and evaluate decisions made by politicians, they cannot know all the technicalities of a political decision making process. Just as a senator will hardly have a clue of how to cure a cavity, what string theory really is, or when a VPN Tunnel is needed.

But, worst of all, pure Direct democracy implies that Citizens ultimately give up their freedom to be doing something different that Politics. One basic, simple reason for representative democracy in modern, complex societies, is that a Citizen may want to (and, for the common good, should!) be a farmer, or a dentist, or a scientist, or a software engineer, or a lawyer, or a teacher, or else, and not necessarily a politician.
