It’s a bit more far reaching than just people having to fill out a form. It’s a matter of principle. Just imagine that every country in the world tries to impose extraterritorial law on everyone, then we would have to fill out 200 forms every time we open a bank account?
And also, the whole US person topic lead to the unjustified abolishment of the Swiss bank secrecy law, which was and is detrimental for our banking industry. The money is now just held in other tax havens some of them even being US ones. The US does not have a right to collect taxes from their citizens living abroad in another country and it does not have a right to unilaterally impose compliance and reporting requirements on every country in the world. Furthermore, we are also not obliged to help the US to enforce their ridiculous tax laws in our territory. In our territory, the only obligation we have is our own law.
It’s like if Saudia Arabia would come to the world and say, look guys, in our country we have the Sharia law and our women need to wear a Burka. We now demand this law to have extraterritorial effect what means all you countries in the world have to make sure that if a Saudia Arabia person visits your countries, for business, for leisure, for whatever, you have to make sure that they wear a Burka at all times. Every hotel, every business, shop, whatever that provides services to a Saudi person has to enforce this law, otherwise we will fine you with multi-billion dollar fines and impose sanctions on you. We don’t give a damn about Saudi law, why should we care about US law?
Then, it’s also not only about the 99% of the population, it also has a negative impact on US citizens or US person for which it is now very difficult to open a bank account in Switzerland. Most institutions won’t even open an account anymore for you if you’re a US person, so you’re restricted to a few banks that are an exception.
So it’s not only about the form, this form of imperialism had far reaching consequences on our economy, our companies and their business models. Their interference had a huge impact on our own legal system and if any other country would even try to do something similar with the US, well the outcome would probably be not very well. And it also has far reaching political / geopolitical consequences as we gave in as a (allegedly) sovereign state to the blackmailing of another country. It makes us a vassal.
We have to pledge allegiance to the imperium or we face fatal consequences. The impact is way more extrem than just filling out a form.
