I think it's reasonable for everyone to have their own cluster if their day-to-day work involves developing cluster-scoped resources. Admission webhooks, service meshes, CNI plugins, etc.

I agree that most people have too many clusters, using them to separate batch and interactive jobs or staging and production jobs. Generally, computers are expensive and manually scheduling jobs to clusters reduces utilization, so it costs a lot of money. It also gives you less operational flexibility, like being able to throttle batch jobs to scale up interactive jobs.
