Some people act like non-monogamy is easy. That it’s just cheating or promiscuity disguised. But, if you’re doing it right, it requires emotional intelligence and endurance, the self knowledge to be able to set good boundaries and the maturity and empathy to respect others’. It requires a good amount of time, effort, and resources. Negotiating schedules, balancing the needs and wants of each involved, etc. Even those who do it selfishly (or worst case, abusively) would need to expend energy hiding their ways from the community at large (which honestly seems more exhausting). And it’s not like monogamy let’s you avoid those types of people.
