Regulation, standards, and rules

The mechanism

Once a company becomes critical infrastructure, the state stops being a regulator and starts being part of the moat. TSMC makes the most advanced chips on earth, and it has been treated as a national asset since its founding: the Taiwanese government was an early investor, and the company gets utilities, zoning, and a university talent pipeline arranged around it, because the country's prosperity and its security now run through those fabs. After 2022 the same logic went global, with the United States, Japan, and Germany all paying TSMC to build fabs on their soil. When governments compete to subsidize you, you are operating with an advantage no purely private competitor can buy.

The tension

The trouble is that protection and capture are the same relationship seen from two sides. The political backing that shields TSMC also makes it an instrument of other governments' policy, exposed to export controls and pressure to move production it would rather keep at home. The deepest version of this is geographic: TSMC's leading edge sits in Taiwan, and the concentration that makes the cluster so productive is also the single largest geopolitical risk in the global economy, which the foreign fabs are meant to insure against rather than solve. A moat built on a political relationship is only as stable as that relationship, and that is decided in capitals the company does not control.
