There's so wrong there i don't even know where to start.
a) space costs money. who pays for hijacked space ?
b) if the new ISP goes dark, why does the old ISP get hit with a DDoS  
destined at the former customer
b.1) how does the old ISP protect itself from such a scenario ?
c) if a customer multihomes to an ISP B that buys  transit from original ISP  
A how exactly does that work ?
d) why should I accept a more specific for a netblock I'm announcing ?
e) why do I need to inject the internet into my IGP which is otherwise simple  
?

If you compare internet routing and PSTN "routing" seriously you've never  
worked with at least one of them. PSTN "routing" isn't, number portability  
takes days to deploy, PSTN doesn't have efective multipath and please do take  
a look at the portability mechanisms.
