What is the biggest problem to solve? Would it be enough for ISPs to make 
sure that they will not send out packets which didn't belong within their 
PA blocks, or is it that one user shouldn't be able to spoof at all (even 
IPs adjacant to their own)? Would the global problem go away if global 
spoofing stopped working?

I of course realise that it's best if user cannot spoof at all, but it 
might be easier for ISPs to filter based on their PA blocks than to (in 
some cases) purchase new equipment to replace their current equipment that 
cannot do IP spoof filtering.
