I didn't say it's free, only that it's relatively cheap. That RAM can simply be used for caching is incorrect, though. There are very-non-neglible costs to maintaining caches in distributed systems.

It’s not clear what you mean by a distributed system in this context, but RAM is used for caching, costs or no.

My point is that you can't increase the cache size indefinitely to get performance improvements, because you also have to handle cache invalidation. There is an optimal working set.
