On a non-networked system this is true -- create pseudo-users
and pseudo-groups as needed and use their symbolic names.
Once networked systems come into play and user ID and group
ID values must exist across shared filesystems, and in the clustered
system case, shared CPUs, having a space in which to reserve
(hopefully) common user ID and group ID values becomes more
important.
Of course, this is also an argument for network identification
schemes, such as LDAP and NIS, but for systems where the
burden of LDAP or NIS is unacceptable (and that's not a decision
for anyone but the system administrator to make), having a
reserved space is needed to make this possible.
