You missed an option. Just change to another ISP. I know of at least one AS701 address block still attached to a company that hasn't been their customer for ten years or so.
How is that possible? AFAIK no local politician has passed an IP address portability law yet. If my circuit from VZB were disconnected, wouldn't they release the address block for reuse by other customers just like any other ISP?
The government doesn't own IP addresses so there is no need to pass any such laws. I suppose it is completely legal to sever a transit agreement for traffic with a provider but maintain a business relationship where you pay them a fee for the use of the IP address space. There have been several instances in my career where I have used prefixes issued by a carrier that I never announced to them. I was using their IP space but the traffic to those addresses never went through their network. In some cases I have maintained a relationship with them such as having a thin pipe where I might pay some small monthly fee in order to retain the IP address space but simply paying someone to allow you to keep IP addresses isn't beyond the realm of possibility.
