Well since direct democracy initiatives also have plenty of time to research and make informed decisions about, what's your objection? If you have the same people making the same decisions with the same information and the only difference is whether you're counting a fraction of people or not, what's your damn point?
You don't have the same people with the same information; you have the entire population of the country. They have
time to research and make informed decisions (though most won't have access to the resources, and most also wouldn't have the inclination to research)... at least for a few votes. In a full direct democracy, everything would be up to public vote, so someone with a full-time job realistically
wouldn't have the time, even if they
did have the resources and inclination.
Let's imagine that a trade deal is required. The country needs more silicon, else they'll be looking at a severe computer chip shortage in a few years.
Now, the vast majority of people do not know the stock is low, and nor do they know that computer chips are composed of silicon. So it's unlikely the trade deal even gets
proposed in order for it to be put to vote.
But, say that the country gets lucky, or the press actually does its job and enlightens enough people to the issue to get the trade deal proposed. Only 99% of people have zero fucking idea how much it costs, or have any experience of negotiation or diplomacy. Maybe they organise an election for a board of people to draft it... only nobody knows anything about who has the expertise in the area, so it's essentially a crapshoot.
If the stars align, it'll get drafted and go to the people for confirmation in a referendum. But damn, that cost looks high! It gets voted down by 51 to 49%, because the costs look high and people don't really know why we need this silicon anyway, we'll do fine without new computers anyway. The press obviously isn't providing sufficient enlightenment on the issue, because 1) silicon trade deals are fucking boring, and 2) we're in a FULL DIRECT DEMOCRACY: this is one of
2 dozen referenda on the docket for the week.
So it falls through. And a few years later people find out computer chips are actually fucking important, and their health service administration system collapses because it relies on something that the country doesn't have anymore, which is also something people don't know the first thing about.
