Another point, internal and external loops don’t just differ in speed and locus of feedback. They differ in purpose. Internal feedback is about deciding what’s worth doing, external feedback is about figuring out if it works in an environment. QA is secondary in both.
QA (quality assurance) is actually a trivial cost/risk trade off. Both you and your reader can detect typos for examples. Whether you do an extra copy editing pass or let the first few readers find them and complain/point out is just a cost/risk decision.
Setting aside objective harmful risks (anything from consumers spending non-refundable money on bug-ridden things to planes crashing) QA is actually a function of the king of consumers you want and how foolish you’re willing to look.
I am fairly willing to look foolish and tend to solve for readers who will be forgiving towards rough edges in the interest of getting to sillier, more speculative places. If you can’t get past a misplaced comma or misattributed quote, you’ll hate my schtick anyway
