Why do people seem to think buying a house is such a good thing?

So much of the time, I see it treated as a given that whoever you are you must want to, because that’s just what people do, but I don’t know why.
I’m always seeing people set “buy a house” as one of their life goals.
I never felt like owning the place I live would be worth it. I’m not really sure what the big advantage of home ownership is supposed to be. I can think of more disadvantages than I can advantages.
Is it overrated, or am I just ignorant?
