AMD blew it with 5600X pricing is past tense, and you're comparing it to a future tense hypothetical processor that doesn't yet have a launch date, final specs, or price?
How did you work that one out? As far as I see it, the 5600X is priced against intel 10th Gen and it's sweeping the floor with them.
If you somehow believe that there won't be an AMD answer to Intel's 11400F when it hits the market, then you need to take off your Intel-branded spectacles. AMD and Intel price things as high as they can get away with because they're in the business of making profit first and foremost. If the 11400F is a great gaming CPU for budget gamers, then that's great news but don't expect it to sit far outside the price/performance curve that both AMD and Intel use to extract the maximum profit from each model. Chances are high that AMD will release a vanilla R5 5600 at that point, probably close to the $200 price point, but subject to change based on Intel's pricing of the 11th-gen i5 models.
