Of course it's is valuable. Complexity makes software expensive to make, so removing it is literally worth a lot of money that can be better spent making features. Nobody buys software because it's accidentally complex, they buy it because of features, quality (which is something that's also affected by complexity!), etc.

The only reason complexity is prevalent is due to a shortage and geniuses (and also a shortage of "Some" too, if we're going by Alan Perlis' quote).
