IP addresses are dynamic, 2 customers with the same NIC MAC can and frequently do battle over an IP address. How can they prove who had what, when?

Yes, all ISP's keep detailed IP assignment (for a period of time), or they should.
Simply, an ISP keeps a DB of its IP allocation mechanism, what IP address was assigned to what user on what date/time (based on radius user name or some other mechanism such as modem MAC).
In relation to the NIC MAC assignment on cable networks, you can't have two or more of the same client MAC and Modem MAC on the same uBR. If two or more customers had the same NIC MAC, they would likely be on different uBR's which would mean different IP ranges, hence seemingly accurate IP assignment data.
