Well, the larger ISPs use routers that can handle more than 240k routes, 
and as long as they carry the routes, if smaller ISPs filter they will 
soon see a loss of customers due to this. I also forsee these smaller ISPs 
getting a default-route as well from their upstreams to handle their 
inability to handle all routes.

Well, IPv6 solves the addressing issue but it does nothing for the routing 
issue. Multihoming in IPv6 is still an issue being debated due to exact 
same reasons you mention.

Probably because the solution is a radical change from how things are done 
today and people are quite hesitant to commit to a paradigm shift, 
especially since the "throw faster hardware at the problem" has worked so 
far?

It would of course be interesting to send the proposal to groups like 
NANOG and see their reaction, as there are quite a lot of more routing 
people there that cares less for addressing.
