I do more enterprisey stuff so our customers are a little less accepting of model restriction. I find a service based architecture more flexible as its pretty easy swap out services that just work off a common currency that define different or customisable behaviour. The sort of situation where an entity is performing business logic makes that harder do as opposed to swapping out the service.

I made the same mistakes as OP and learnt the hard way. I encourage you to explore a greater purity in your models in the future because I genuinely believe it leads to better code.
