Unrealistic? That's a bit strange because its actually quite normal for wooden structures of larger size/volume if you really are wanting to compared real life.

As you progress in the game and gain other building materials and learn how to build properly with them, you can get away with using less supports that you feel are obtrusive to your building wants(possibly).

All in all this building system in Valheim is pretty solid. You just need to learn to build with it more is all.
