In the presence of specifics, it would still be rational to assume the very worst. If we overthrew the government for a plausible movement to create a scarcity-free utopia, we still most likely wouldn't end up with such - the kind of people who seize the reins of power don't sit idly by just because we're hopeful. And correct me if I'm wrong, but this is the major reason you're having an allergic reaction to what I'm saying.
But don't worry, democracies usually aren't overthrown. And this one, being ultimately ruled by capital, certainly won't be. But it still is dying, and may even get there in our lifetimes. In the worst case, it will face this long period of decline followed by ultimate economic and thus societal collapse. This process will not be pretty, and we can only hope that whomever fills the resulting power vacuum isn't preaching a message of a scarcity-free utopia, if you know what I mean.
The better outcome is one in which this failing husk of a nation is used to incubate (and is slowly replaced by) more agile and sustainable methods of societal interaction and coordination - based on voluntary interactions on the Internet. For rough examples, we can look at the positive ideas of cryptoanarchism for example implementations of various things (and please note that these technologies evidently play out much differently than was forseen). We don't need a "first amendment" and constant struggles to define a uniform meaning of freedom of expression for 300M people. We can codify the first pass of this concept by running TOR, and let much smaller autonomous groups use the resulting environment as a starting point for refinements appropriate to their community. Likewise with economic policy and many other issues that are currently centrally and unaccountably dictated by Uncle Sam. There's obviously a whole host of things I'm not or am unable to address, and focusing on any particular philosophy/technology is missing the larger picture (which is why I avoid doing so). However, the beauty in this approach is that if you decide you don't like it, but still believe in everyone's right to be generally left alone, you can simply not participate.
