Yes, there is a reason for it: it is rude.

It is better for privacy and receiving clients, but a disadvantage is less physical space in the center/walking area. You can play with lego on the ground, too. I would also get rid of the bookshelf. Get an ereader. There is no way you need all those books physically in your vicinity (I am not arguing you should give up 100% on physical books).

Worse, if my desk wouldn't be at the wall (in corner) my cats wouldn't be able to hide in that corner under the desk, and they could play easier with cables which would also be way more in sight. Against the wall? Not so much. I do regret not getting a sit/stand desk, but the extra cost back then was too large. Oh, and I like Ikea. You can sell those refurbished for good price, too.
