More like a Techno-Capitalist Fantasy. This part had me laughing out loud:
> Markets prevent monopolies and cartels.
No, markets naturally culminate into monopolies and cartels. That's just human nature.
History has shown over and over again that monopolies and cartels are naturally occurring and that the only successful way to deal with them is to break them up via government intervention. Sure, some monopolies may eventually dissolve due to things like technical obsolescence but that's the type of thing that takes so long that entire generations can come and go, suffering the effects the entire time, before they break up.
This manifesto also doesn't seem to have a solution to "natural monopolies" like ISPs or utilities (water, sewer, electricity). It just pretends such things don't exist.
It also doesn't have anything at all to say about economic externalities (e.g. pollution/downstream impacts), policing of bad behavior, or "tragedy of the commons" sorts of problems.
If you had a technology-oriented country that sends all of its pollution to another country it could be the perfect world envisioned by this "Techno-Optimist Manifesto".
