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.
IPv6 allows organizations to REDUCE the number of prefixes that they announce in the global routing table. Most ISPs will only announce one single /32 route in IPv6. This makes a big difference. The debate you refer to is whether or not someone can invent a newer and better way of handling routing in IPv6. Even if they never succeed at this, the same old BGP4 multihoming continues to work with less routes in the IPv6 global routing table than in the IPv4 global routing table. --Michael Dillon
