Using a random Wifi hotspot when traveling is an act of insanity without a VPN. There are some bad guys that use VPNs, but so do many affluent, tech-savvy business travelers. This group, which is highly coveted by Visa/MC, will now be introduced to and eventually become comfortable with Bitcoin. It's like Visa had an all-hands meeting to come up with the best way to drive their target customers to alternative payment methods.

Well, I agree with your first point, but I think you're overstating both the carrot and the stick of the alternative. The corporate users have company VPNs; the solo road warriors / lean startups can (already do) rent a cheap VPS for tunnel egress. And whatever your personal view, Bitcoin still sounds like snake oil to most people.
