It is revolutionary to say specialization doesn't apply to countries, no matter how many times someone on HN says it. Removing competitors in other countries doesn't add competition to the market.

> Ore isn't really specialization at all, it's resource availability.

You just made that up. What is it based on? Also, resource availability is definitely part of specialization - countries specialize in what they can do more efficiently than other places, which depends partly on resource availability. It also depends on infrastructure, capital, laws, regulations, skills, labor, and many other variables.

People haven't copied Apple and SV because it's very hard to do it. Nobody does it with any successful company. You just can't copy those things.

> Not be dependent on a single supplier

Again, by reducing suppliers - and essentially worldwide in this case - you reduce competition. Now the public subsidizes a local supplier who is not good enough to compete, and therefore the public also gets a substandard product with little hope of competition arising.
