Unrelated? I' beg to differ. More to the point, all systems have an access control model. It could be explicit or implicit depending on how the system is built. Regardless, it defines the barriers and boundaries between everything in the system.

The comment suggests that just by separating things in the popular sense of microservices results in a barrier to enforce separation of concerns. That's how I read it, at least, and I find that to be is misleading.

This is the crux I see around popular discourse of microservices. It's often presented without a broader context.
