All these are a given in most developed countries. Corporations and funds aren't headquartered in Ireland for the great Irish infrastructure or because there is better rule of law there than in France. What many seem to be forgetting is the entire economical aspect of it. Economies are not all the same, some are stronger and some are weaker. Some are naturally attractive because of the talent pool, location, other businesses settled there, etc. Others aren't and might need to lower the tax rate to be able to compete. Adjusting the rate is an important economic tool for governments, losing this will cause some countries problems, the same way some countries in the Eurozone are now suffering serious consequences for giving up sovereignty over their currency and losing the ability to devalue it. A border adjustment tax theoretically avoids these problems and might be a much better choice for the smaller countries that aren't the US and don't dictate the rules.
