I think, your vision of capitalism is too far from reality.
For example, bureaucracy is not part of capitalism, it is only possible solution for large share of humanity problems.
- Big planes, like 747, only possible with bureaucracy, because their complexity is too high for any other form of organization - to build one 747 need about 600 human-years.
- Imagine mutualism way of build such machines - they will be rare, like Great Pyramids, and customers will wait at least few decades for each plane.
Capitalism just pay for bureaucracy, because this is effective form of organization.
And private ownership with one exclusive owner, is most effective form of ownership, all others magnitudes worse.
So you could talk about small projects without capitalism, not about large projects.
If it will be easier for you, imagine world in which every civilization achievement tied to only one country, and impossible to move production to other country, and all other countries are constantly bargain for scarce supply.
Imagine for example, all commodity automobiles produced only in Germany, by Daimler and BMW.
They are good automobiles, but without bureaucracy nobody could copy them in big enough quantities, even Volkswagen is impossible without bureaucracy.
It is impossible to build PC without bureaucracy, only small, garage size firms.
To imagine, what is garage market like, read:
