So my point was that unless you know everything about life and the universe you might not know what your preferences are (and preferences change) ;)
And not all gifts are material.
But sure, there's nothing wrong in not wanting anything from someone else if that is your thing.
I get the impression going through this gift that people don't actually know how to give gifts. I LOVE giving gifts. No, I don't go through someone's Amazon wish-list or buy them something they could buy themselves. I usually make people things, and it usually takes 2-6 months of work. I might spend a month on an embroidered pocket square, or a handmade notebook, or a handmade piece of jewelry or carving, or an elaborate 6-course meal and paired wines.
If I can't dedicate at LEAST few weeks to constructing the perfect gift/experience for someone, I won't give anything at all. Better nothing than a bad gift...
Of course it is possible than someone would give me something really nice, it happens with some of my closest friends and relatives. But in the case of strangers or people I know for 1 or 2 years only the chance of a bad surprise and its consequences, such as having to pretend I like gift and worrying about questions about it some time later, outweigh. The risk is just too high.
That sounds like a closed mentality to me, you never know really, someone might just surprise you.
