Why do people always associate cqrs with microservices?

I have a project where only 3 developers work; we re designed it to be cqrs. I was sceptical at first - I especially don't like some of the boilerplate it creates - but I'm now sold on it by combining it with the mediator pattern, now I can have validation, logging and performance checks on every command and query without repeating code, works like a middleware

And ofc being only 3 devs it would be nuts to have microservices so we are happy with a cqrs monolith
