Disagree. A government can be held accountable. Some asshole ex-hedge fund manager attempting to corner the market on a drug can't be.
Accountability is not really the main measure we care about (though it's related to it). It's efficiency. We only really care about accountability because its supposed to increase efficiency. People are supposed to get punished when things are running poorly.
The problem is, no one really gets punished when large government organizations are running inefficiently. The business does not go out of business. There is no competition. There is no real incentive to innovate and beat your competitors.
I think we need to reevaluate pharma law. But I don't think replacing the current monopoly with a government one will do much good of anything.
I've long held the belief that whenever there is a supposed failing of private enterprise- it's almost always actually a failing of government. I've yet to be proved wrong. Government makes the barriers of entry too high in the drug market. It's way too easy to have a monopoly because the government basically grants you one.
Doable. But I think you put too much faith in the government. The government is a natural monopoly itself. If they're doing a shitty job you don't get any other options.
