I may have valuable and confidential data, and I may have customers
who could sue me if I lost their data. Why does having the same
user/pwd make a difference to security on a small private network?

If they get access to any of the machines then all is lost anyway, as
I have ssh access between them using keys. Are you suggesting that I
should not allow access between the machines using keys?

Well that is not what you said initially. You said it is a "really bad idea".
