The claim that you’re transparently passing the savings of tax avoidance onto consumers rather than charging market-rate and pocketing the difference is both unlikely and unprovable. And even if you were charging less, this would essentially amount to an unfair, extra-legal competitive advantage.
It is not unfair, and it is not extra-legal. Anyone can offshore their company and in some cases it can take less than an day (incorporating an LLP in the UK takes a couple of hours) with virtually zero barriers of entry, all fully compliant with the relevant legislation.
If legal regulatory arbitrage (through tax havens) is unfair, then the corollary is that any kind of business profit arising from utilising uncommon knowledge is unfair. I think this position is untenable.
This syllogism is so unsound that I’m not sure how to respond. I don’t think I’m arguing that, and I don’t think that using corporate tax havens is merely “using uncommon knowledge.”
Then why are you using a pseudonym?
To clarify, I don't necessarily agree with his position, but I disagree with your proposition that he is using a pseudonym for that reason.
