you can craft all the laws you want, the mega-tech companies will always cluster in SFBay. If you're Dutch and you start a subsea oil exploration robotics company you will certainly open an office in Houston. And then your biggest customers and market will rapidly be Houston, and so your largest office becomes the head office. If you're Colombian and invent a brilliant trading algorithm, you will probably move to New York, regardless of the laws in Colombia.

This is just common sense. The best bet is to proudly foster these small companies which go big overseas and also have an ecosystem of smaller players who don't have huge multinational ambitions, likely also funded by these unicorn exits when the money recycles locally.

Of course, tune and craft laws and regulations to create the most output. But stop trying to fight this clustering effect...
