Of course! There is more than one concept that has value. And each concept also has a price (or price range as there will always be multiple implementations of each concept, each implementation will deteriorate over time and so on and so forth). There will always be more than one class of consumers, more than one set of value/costs preferences. Otherwise we would only have one programming language, wouldn’t we? So acknowledging one concept has value doesn’t mean announcing that it is the only concept worth existing.
