I also forgot to mention the insane amount of resources wasted lobbying to complicate the tax code so every company and sector gets their loophole. This doesn’t just have the same human capital cost but it also gnaws at the trust people have in the democratic system. It’s a lot harder for Bezos or Cook to lobby for an individual tax cut than it is for Amazon and Apple.
If you really want to start from first principles, corporations may seem to be financial pass-through entities but serve as legal shields. Shareholders are not personally liable for externalities like environmental catastrophes or labor law violations. Elon Musk isn't subject to incarceration when someone is killed in an autopilot failure.
If you believe that corporations should also pass through legal liabilities, then sure it makes no sense to pay corporate taxes. But that's not the world we live in.
