I'm surprised with some of the responses you've received on this.
But I absolutely know what you are talking about. I often SSH into new machines, that I may not have root access on, that may not even have internet access, or be a distro with a package manager (e.g. some switch running a custom distribution).
In those situations it is a huge advantage to know the tool, rather than try to do some gymnastics to get your tools onto the box or the data off the box.
These "old" and "broken" tools are installed as defaults on all these systems for a reason.
