No, there are thing that are better on disk than in memory. The most common example is tmpfs. It's much better that files left on tmpfs can sent to disk rather tying up physical memory indefinitely. BTW you mean paging, or swap use, rather that swapping. Linux supports only paging, so it can be taken as read that swapping means paging, but FreeBSD supports both.
