While it is easy to start with monolith, it's not easy to just go from monolith to Microservices in case it is determined that's the best path forward. Often organizations don't have the luxury to "learn" by doing a monolith first and then determining the boundaries. In most cases, market pressures, limited budgets keep monoliths monoliths. OTOH, my experience is that it is easier to combine overly granular Microservices into just right size Microservices on an ongoing basis. And yes, infra requirements are bigger for Microservices, but often it is highly automate-able.

I think, one of the reasons, besides all the usual reasons, that keeps Microservices in vogue is the ability to align with organizational structure and enabling independent-ish teams.
