Honorable senior, I admire your wisdom and insight.
I agree with your argument that 3D printers will make individuals the subject of production and consumption.
3D printers will make individuals into corporations, eventually distributing decentralization to the world.
However, Korea is an environment where individuals cannot create their own business by owning 3D printers. Most Koreans are poor, and there is no market in Korea to produce and consume 3D printers.
So, the Korean government and corporations rely on US capital and technology to produce 3D printers. 3D printers produced by Korean companies are for overseas export.
On the other hand, a handful of Koreans use 3D printers made in China for $ 130.
The $ 2000 Korean-made 3D printer is consumed by Korean government agencies and companies.
On the other hand, Korean folks rarely use 3D printers.
The Korean government and corporations have produced 3D printers to earn dollars, so Koreans' interests have been ignored.
The situation is similar for Korea, China and Japan.
They are sacrificing their own people for internationalization and globalization.
In East Asia, 3D printers have become a tool for centralization of national governments and businesses.
Tech advances. When it does, it advances more quickly.
Today the situation seems hopeless, but tomorrow will come victory. I watched a video of a guy in Australia who made a cruise missile (without an explosive payload) in his garage. Cruise missiles cost the government ~$1M. He made his for ~$5k.
DIY is the common cure for being priced out of markets.
wow, It's amazing that an Australian man made a missile for $ 5,000. Probably Koreans will also make their own weapons in warehouses. Warlords around the world may be afraid of the terrorism of the lower classes.
As you point out, the Korean government restricts high quality 3D printers out of fear Korean people will make weapons with them.
He didn't have a 3D printer though. Just a good shop full of good tools, and the skill to use them well.
Koreans who are dissatisfied with the Korean government secretly make weapons and bombs to commit crimes.
They sneak make guns and bombs without a 3D printer. As you pointed out, Koreans who resist the dictatorship of the ruling classes have begun terrorism.
IMHO they should make solar panels, machine tools, and aquaponics instead of bombs.
I'm glad some Koreans are rebels. It may make life more difficult for some Korean people, but it is essential that people with the courage to say no to overlords resist.
Some day the empires will collapse. We will all need that spirit of independence then.
