It doesn't simplify it, it just moves the arbitrary line. Inscriptions didn't exploit a vulnerability. They used witness data exactly as taproot allowed. Calling that exploitation is like calling Ligh...
It's not arbitrary, taproot was activated on block 709,643. From that point forward it was possible to include larger chunks of non-financial data in the blockchain, but that was not the expressed purpose for activating taproot. Since this was an unexpected outcome it would be reasonable to categorize inscriptions as an exploit.
Lightning facilitates financial transactions and while taproot provided some improvements for lighting it doesn't rely on taproot so that's not really relevant to the issue at hand.
