Lol. The government provides stable society which allows for any company to function. Without government, Musks and Jobs of the world wouldn't even get to their first million, as they'd just be robbed and killed on their way there.

How about providing infrastructure, a stable economy, peaceful society, etc. ?

My six years of dept free, tuition free education in computer science earning me a M.Sc. with government student housing subsidies and monthly pay is "the government doing absolutely nothing"?

And it is morally warranted that I do what I can to avoid paying taxes when I employ online?

Only if you think one-dimensionally.

Consider the ultimate cause and effects and you'll get closer the truth.

You mean all those companies that grew and educated their employees in test tubes on Mars from whence they telecommute using their own inter-planetary network infrastructure?

Or, we can enforce the spirit of the law (companies with equal profit pays equal amount of tax or similar) rather than enforcing the letter of the law. You know, how we deal with lawbreakers otherwise. It's exactly the reason we have space for interpretation in laws in the first place.

The problem is that there is a risk/compliance trade-off.

"The law" is not a compiler that compiles or not. Heck, companies can report whatever they want and get away with a certain chance. If you do the math it might even be probabilistically beneficial. But that does not make these actions social or socially beneficial or morally right.

well, the European rule is that the HQ of a company for tax purpose is where its orders are actually coming from. I don't have this vibe here.

Because companies are run by people? Shell companies don't just spawn on their own...
