Again:

Why is this discussion so fixed about basing policies strictly on 
prefix length? And also on the value of /18 which just *happens* 
to be the value chosen by *one particular* ISP?

This is not a fact. It is a possibility.

Another possibility is to watch the total number of prefixes routed,
possibly charge for routing each one, and not arbitrarily restrict 
prefix length. 

The goals of address space conservation and routing aggregation will 
always be somewhat conflicting. Compromises have to be found. This is
the daily business of Internet registries and ISPs. 
Just a fact of Internet life.
