The modem is connected 24x7. What is the purpose of Dynamic vs. Static

That's the point - with @Home a static address IS concurrently in use. You
get your cable modem and its up, period.
Caveat - I'm discussing 2-way 24x7 @home customers. There are markets where
the service is 1-way, I believe, and in THOSE markets, dynamic addressing
makes more sense, because they're NOT all up 24x7 (if they are, the
Cable-ISP's modem pool is going to get large)

That's one advantage of DHCP vs. static, BUT it isn't a technical issue
that ARIN needs to concern itself with in regard to address space
allocation, its simply an issue internally as how (not) to piss off your
customers.
