If you're like most people working off site, there are a few hosts that 
you need to keep long TCP sessions open to, and the rest of the net that 
gets random traffic.  

It doesn't look to me as though the loss is being introduced at the
NAPS. If you look at the trace, you'll see that significant loss
starts to appear within Alternet, well after MAE-west. 

Traceroute is less useful a tool than you think in the face of congestive
loss.  Routers can and do selectively prioritize the queueing packets
based on their type, and if I were a network operator I would have no
hesitation about dropping traceroute or ping packets to low priority.

If I did interactive work under these conditions on a regular basis, I'd
have gone insane long ago.

No, you would have changed ISPs a long time ago, instead of whining to 
NANOG that the entire world is providing sub-standard service.
