Commodities only have the commodity-value (i.e. price); actual value (i.e. something's worth/weight/utility/what something means to you) is unrelated to commodification. Most valuable things in your life likely have no meaningful commodity value. Very much including the concept of friction.
If only commodities are "valuable", the word has lost all value.
Most software development is a lot of low value commodity stuff that you just have to do properly just in order to do whatever it is that makes whatever it is you do valuable/unique/desirable. You can' charge anyone extra for doing this commodity stuff right. But if you do it wrong, your product becomes less valuable.
A good example of something that is both a commodity and a common source of friction is all the signup and security friction that a lot of software providers have to do. If you do it poorly, it creates a lot of friction, hassle, and frustration. And support overhead. It's literally costing you money and customers. Doing it right isn't necessarily directly appreciated but it results in less friction, frustration, and overhead.
That's why good UX is so important. It's a commodity. But there's plenty of opportunity for turning that into friction by doing a poor job of it.
To give a non-software example: think of wearing a clean shirt in a job interview. Nobody will hire you for the clean shirt, but plenty of people will reject you for stains.
I think negative value would look something like bombing someone. Negative relative-[commodity-]value does not imply negative value.
Also, software is not a commodity at all. There's no cost to reproducing it.

I'm not sure what you mean by "commodity". I think you mean "commonplace" or something like that.
