You didn't really read what I had to say if this is your response. I said they should think about it but the options to solve are relatively simple, I already said in the very beginning it wouldn't alter simple choices due to the very simple solutions. However if aggravated then yeah it probably would, like if we had like 12 jobs on strength/intelligence and 1 on dexterity/mind then yeah it would actually have obvious effect on market and should therefore be on their decision what to do next. Also they do attempt to get people to use the main stat materias at varying times, such as certain quests, or accessories as you pointed out (main reason why Strength is ~500% more expensive than other main stats) - the demand at those points would exemplify their balance. I never said they couldn't make it unbalanced (only that drop rates being adjusted slightly would be useful), and if you're suggesting higher demand with same supply has no effect on a market... then yeah (Main stat materia definitely sell, consistently, so they have value - and strength is currently out of the norm).
All they need is to be mindful of the rates and what jobs need (obviously somethings never change like det/crit). That doesn't mean "oh no its not balanced, lets make a dex job now!" it just means you don't run around blind saying "nothing matters" as that's how you make mistakes. It also matters their group (gear group), but w.e I'm trying to explain what I've already said "simple issue, simple solution". And clearly you're set on thinking im banishing multiple stat desires in a row or something, which I've never attempted to say.
And the market should always be treated as precious, market is not some flippant thing you do whatever you want with when designing. All things are important. Always, that's why they hire dedicated economists in many MMOs.
I said in that thing you quoted imo, so clearly i m o...
