On voting: here's my proposal. Vote with touchscreens. When you're finished, it prints a scantron-style page, perfectly marked. No hanging chads, no pencil marks, no erasures, nothing: just "[X] My Candidate" filled in. That's what you drop into the ballot box after looking to make sure it's correct. Go ahead and use those for instant results so you can know a minute after election who (provisionally) won. But if there's suspicion - or who knows, maybe always? - the marked ballot count wins. This is a hybrid of the current system with its protections, but with the advantages of easy UI and instant results that people want.
I think free-as-in-BSD market is mistake to Libertarians (of which I'm registered as). I think the rule of government in the economy is to protect the freedom of the market, not necessarily all of its participants. For example, look back to Standard Oil. I think it was completely appropriate for the government to break it up to preserve the open flow of the economy and to prevent a single company from completely dictating how a major economy segment operated. When Standard Oil had complete freedom, the result was little to no freedom for all the other actors. I view it as analogous to banning slavery. Sure, that placed new restrictions on some, but that cost pales in comparison to the value of freedom it granted to others. That was a good trade.
Now, I want those government actions to be rare and as gentle as possible, but I still think they're necessary. I don't want a completely unfettered economy where any large player is free to bent whole markets to serve solely themselves. That's been tried many places and times, and it never works out well (either for the other actors in the short term, or for the monopolists in the long term when enough people get pissed off that they revolt).
