An excellent post on the problems with the foundational theory of epistemic justification, Jack Simth!
But your argument seems to apply to everything and so appears to deny that there is any objective truth to anything whatsoever, leaving the door open to things like Holocaust deniers, the Moon landings never occured theorists, Masonite conspirators who are so skilled at manipulating world events that the lack of evidence of a conspiracy and itself evidence of such a conspiracy etc.
I think that in order to maintain that objective truth is still possible (albeit in a weakened, post-Kantian form of the term), while still denying that "objective morality" is possible, requires more elaboration on the whole Hume / G.E. Moore thesis that it is impossible to derive an "ought" from an "is".

There's a catch when using the above on logic, applied science (but not purely theoretical science or history), and math: you can test and demonstrate those to a reasonable degree, to see if they are "right". You can't do that with ethics. Take, for example, the case of the innocent fat man (for those of you unfamiliar with what I am talking about, it's a scenerio for philosophers of ethics: a fat man goes into some sea caves to rescue some lost tourists. He finds them, and leads them out. Unfortunately, he gets exceptionally stuck, with his head above the high tide mark, at the exit, with the tourists stuck inside the cave. The tourists find they have a stick of dynamite and a match. If they do nothing, they will drown, but the innocent fat man will survive. They can also blow up the innocent fat man, killing him, to unstopper the exit, so they can survive. The innocent fat man wants to survive, even knowing it would cost the tourists their lives (they wouldn't have a chance at survival anyway, were it not for him, after all). However, he can't act, and his actions are not the focus of the exercise. The actions of the tourists are. Do they blow him up, or not?). Even assuming someone was evil enough to arrange the situation as a test, all that would reveal is what those tourists
would do, not what they
should do.
Math is concerned with the rules of the game; what "ought to be" is immaterial compared to what the rules of the game say.
Logic is concerned with "given set A of starting conditions, and set B of operators, is it possible to prove set C of conclusions?" ... but you have to have a set A of starting conditions and set B of operators, and have them be beyond question for the discussion; lacking such, logic gets you exactly nowhere; but that's okay - Having the A and the B to get the C is what logic is all about; it's where logic lives. If A and/or B is false, the conclusions C are untrustworthy. That's implied from the start of the game. Logic is about what's true given some specified set of circumstances. If those circumstances are false, that particular logical proof simply doesn't apply.
In the applied sciences, it's all about concrete, measureable results: how much horsepower does this particular engine design produce? Build it and find out! Sure, theory is used to model and predict, but where the rubber meets the road, it's all about actually trying it, and seeing if you get the expected result. If you are caught in
The Matrix, well, then you are predicting things based on that universe; it's still usefull in that context.
You can't do that with ethics. At best, emperically, you could observe that a society following a particular set of ethics is happier / sadder / wealthier / poorer / more populous / less populous (or whatever other criteria you could choose) than a society following a different set. But before you can pick one set over the other, you must first assume some criteria to pick by; beyond personal preference, you can't really defend such a criteria for long. Is a society where a lot of people die young, but the remainder are quite happy and care free "better than" or "worse than" one where most people live to a ripe old age, but are constantly sad and worried? Which is more important: the rights of the few or the wants of the many? Why? On what basis can you claim that? On what basis can you claim that basis? Why should that particular point matter?
Wait, where was I going with this? Oh well, I got lost. No biggie.
