Of course, there will be no shortage of overly enthusiastic (and absolutely confident) defeatism "We 'can't' do it because x, y, z" (complexities with security, ensuring the person casting the vote is indeed the actual person, excess amount of uninformed populism, etc.) So how about this: for the first <x> years, make it non-binding and simply observe the results. If the votes have no power, so much for the disingenuous claims that "we don't dare try it, and it won't work anyways", because it completely derisks the situation.
So then, when you have people still guaranteeing doom, I reckon there's a pretty good chance that would make a good shortlist of people who should no longer be allowed anywhere near the political process.
I would love to know why people are adamantly opposed to having a honest, transparent, and fact-checked public conversation on the idea.
What about this: for most decisions, people elect their representative, and don't directly participate. The representative votes on decisions in gov't, but their vote is weighted by the number of people they represent (let's call this V).
However, if there is an issue that a person deems important to participate in, then that person gets to directly vote for said issue. Then, the elected representative's vote _for that issue_ drops by 1, and thus their vote only weights V-1.
Hence, by this method, most people who don't give a shit can continue not to, and allow their electoral representative to make decisions on their behalf. But direct democracy is available for those who care enough.
Popular vote is a tool for demagogues and populists and will quickly lead to tyranny of the majority type situations.
Whenever I vote in local elections there are some ballot initiatives, and it's ALWAYS feelgood shit like "give elderly widows whos' husbands worked as a teacher a 25% property tax cut". I vote no for everything out of principle.
Now it is easy to spend lots of money to mislead many people right before the big and expensive referendum, but if a new referendum can happen any day, spending lots of money on campaigns would become unviable.
