People gave their lives so everyone could spend their life studying law?? The people you've got in mind gave their lives for a representative, not a direct democracy.
Laws are difficult and nuanced. Deciding between yes/no takes me a long time, because I am not a lawyer or a legislator. Even for them, again, legislating is a job for a reason... I know I like certain things, and dislike others, I know basically which direction I want things to go; however, deciding whether a concrete bill is a reasonable-enough implementation that has closed loopholes is way out of the scope of decisions I would trust myself, or most citizens, to make well. This, it feels like a waste.
