If I may, it sounds like the hurdles encountered were:
- Paperwork and fees/taxes in each state an employee works in.
- Securing a work visa to enter and work in the US.
But, it sounds like, if we were to swap places and Nitai lived in the US, trying to start a business in Europe, he'd be faced with
- Paperwork and fees/taxes paid to each country his employees worked.
- Securing a work visa to enter and work in the EU.
Depending on the country American Nitai wanted to live/work in, the visa may be easier/harder than the US visa, I'd imagine. But I'm not sure that the kinds of difficulties would be much different.
You're putting up a lot of strawmen here.
Example: "He will pay his taxes in Denmark, Germany, Switzerland or wherever he freely chooses to live. In Europe, you can live in whichever country you like. Most countries here seem happy to receive taxes."
In the US, you can freely live in whichever state you want. It's rhetorically dishonest to compare the United States to a single country in the EU.

I'm sorry that your experience was a poor one. Indeed, US laws are different, and if you went into the experience expecting it not to be different, that would certainly have been a shock. I make no claim our system is better than Denmark's (you shouldn't imply all of the EU is the same as Denmark, by the way). But it's a disingenuous platform to decry the US because you received inadequate counsel on setting up a US business or failed in your due diligence...
I'm sure, however, the pro-European camp of your readership will feel quite satisfied with the tone and subject matter of your post.
