Apple would rather people buy an iPad and a cheaper Mac, e.g. a Macbook Air. And many of their customers do — despite only needing the Mac for one or two things.

These customers, in my personal experience, mostly end up gravitating toward using the Mac more and the iPad less — despite often saying they enjoy using the iPad more. They try to use the iPad for more things, but when there's something they need to do on their laptop, they switch over to using it — and then forget to switch back. Eventually, they give up on the "iPad experiment", and the iPad sits there gathering dust.

But they still did buy it. And likely have had it for long enough that they can't just return it. And they might even (probably mistakenly) think they'll pick it up again someday, maybe when a new iPadOS update makes it more functional and solves their pain-points.

And that line of thinking makes Apple very, very happy. "Buying an iPad you don't end up using because you also bought a Mac" is a situation Apple emphatically does not want to help anyone avoid. In fact, they do everything they can in their advertising to subtly guide customers into bad expectations about iPadOS capabilities, so that they'll end up in that situation.
