Earlier quoted context omitted.
A practical democracy must be an abstraction of a pure, idealistic democracy. You cannot have millions of people deciding on every issue. Democratically elected representatives are one way we can do this. There may be better ways of doing things but it doesn't make democracies not democracies.
> You cannot have millions of people deciding on every issue. From a technical perspective, this is clearly untrue.
It's impossible if you take “every issue” literally, as you are multiplying the number of pdecisions that must be made by each participant per unit of time so much that the time to consider them is non-existent.
It's less impossible if you reduce it to the kind of decisions typically made by a legislature, which mainly just sets rules for executive and judicial officials to apply in deciding more specific issues.
But even then it's of dubious practicality; obviously not every citizen can have a full-time legislative staff, and most of other things besides legislation to devote their time to.
