Having to rely on "some guy hacking some stuff together", in 2025 to avoid accidentally violating visa or tax or some other bureaucratic minutia when there's many governmental bodies/organizations that should have be doing that work since before the Internet even existed seems just totally fine to you? How is this not a free app from some department of the UN? Probably more complicated than "because free apps don't make money", but that is something that late stage capitalism abhors.

I'm not trying to tear down this guy's work, it's a great bit of writing, both English and code, and I'm okay with that pricing model.

What happens when he gets something wrong, simply gets tired of it, or retires, or there's a bus incident?
