It's not claimed to be the "best" way, just one of many possible good
ways. If you can demonstrate that your way is at least as good, go for i=
t.

There is no need for that, since your failure to use a good source of
randomness hurts nobody except yourself.
If you're too lazy to come up with a good method yourself, as most
people are, there are several online RFC 4193-compliant prefix
generators that will save you the effort. At least one even includes
the ability to record your results and be assured (within the margin of
best-effort service) that you will not collide with anyone else who does =
so.
