I disagree with your point that "most of the code are hypotheses to be tested by the market". Most "pieces of software" might be, but I contend that most of the code in most software is under-the-hood stuff that objectively either works or doesn't. If it works, it has nothing to do with the market's opinion. On the other hand, if it doesn't work, then regardless of what a good fit the idea of your software might be, it will colour the market's opinion against you. Using the market to test a hypothesis, and using them to test whether your code works are two different things. The former is a great idea, the latter, not so great. Mixing the two is a bad idea.
