This is a weirdly reductive take.

There are plenty of areas where a "low bar" is more than enough. "low" doesn't necessarily mean bad here, it can simply mean "not the best".

I would argue the majority (in the true sense of the word) of white-collar service work does not require an expert.

It requires someone who has reasonable qualifications in the given field, and the motivation ($) to help you with your task.

So no one needs a top-shelf $900/hour lawyer to draw up a basic low-stakes contract where both parties agree to all the terms as written. You just need someone to ensure that the contract is legally valid as written.
