I can't think of any objective reason why it's not a good thing to be completely delusional and to walk around with your fingers in your ears ignoring the real world, as long as it makes you happy and doesn't harm others.
I can't either. As I wrote earlier, the objective universe would go on as usual whether we were all squawking and throwing our crap at each other.
But there are moral reasons why we should care about truth. For one thing, justice hinges on truth.
More relevantly, treatng diseases requires medical knowledge. It's pretty simple: In order to fix the problem, you need to know what's actually happening.
Science strives to discover and understand objective truths. It's the very raison d'etre of science: to know the truth. That alone makes science moral, even if people misuse it.
