It doesn't scale.  Regardless of Moore's law, there are some  
fundamental physical limits that constrain technology.

Well, there are 6 billion people on the planet.  Don't know how many  
companies or families.  Don't know how many autonomous devices there  
will be (e.g., cars, planes, boats, ships, satellites, light bulbs,  
gastro-intestinal probes, etc. etc.).

You're not thinking big enough.

Any new protocol has initial interoperability problems when it is  
being developed by different people/teams.

a) I suspect most SSL implementations derive out of the same code base.
b) SSL has been around longer.
c) SSLeay had lots of interoperability issues when it first came out.

MS uses PPTP because it meets their business requirements.  The fact  
that it is more practical is a second order effect.
