Everything you wrote is correct. But still, if your product does not transparently show and alert such events, overall product quality is in my opinion bad. Dev or lead or product manager should not be ok with this. But this pretty mich reflects current state of software development. Errors and stuff are in way too many cases "ok" to occure.
I think what the poster is saying is that, as far as the software is concerned there IS no event to alert. You live in the US, but setup the taxes as if you live in the Caribbean? You're responsible for the setup, and as a business owner responsible for either setting it up correctly, verifying that someone set it up correctly or paying the auditors to do that for you.
Yeah it sucks, but the more we try to take the accountability out of the humans and put it into the software, the worse both the accountability and the software gets.
