Making features without any monetization strategy and abandoning afterwards because you can't even justify the salaries of the devs working on it is way better? It's like you're mad at modern product development, ignoring the reasons why.
Making a monetization strategy without understanding the feature is just as useless. If it's new you have to build it in order to understand it. You need to invest some time into the features first. If it doesn't stick then discard it early or iterate on it and use the information gained on building better features.
