Why hasn't anyone built an entirely free computer yet?

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

No. No government would build microchip manufacturing plants in people's garages.
This isn't a problem caused by capitalism. The machines needed are highly specialized and require extremely tight tolerances. Both of those things require a lot of very expensive equipment to make.
You have to remember that we're talking about billions if not trillions of transistors on a single chip. That's not something you can just DIY

It's a parallel. Mao tried to create industry in people's backyards. It took people away from food production, destroyed existing valuable metal products, deforested the areas, and for all that effort, resulted in product with quality so bad it was unusable.
While it would probably also be more like input material production, silicon ingots and wafer slicing and such, I'm sure the quality would equally be shit enough to be unusable. Especially since metalwork tolerances are usually in micrometers at best, but microchips are in the nanometers.
You're vastly underestimating the gulf of complexity between metal fabrication and processor manufacturing.
If this was even remotely feasible, don't you think China would have done it for the several year long microchip shortage?
Yes, I understand there are orders of magnitude of complexity between the two. And no, it's not remotely feasible, like I said, they wouldn't be any good. If anything, I'm agreeing with you that no system of government, or system of economics for that matter, would make it practical.
