Are such Ham links actually of any real use, since encoded traffic
such as SSH/SSL

If someone wants to request a Google search.   There is no way of a router
knowing if the requestor  is sending the packet  for a commercial purpose or
for  a non-pecuniary  allowed usage,  until  TCP gets some new packet fields...

You can be visiting,  And it's  non-commercial
allowed use,  if you're ordering a pizza for personal consumption,  But
those same packets are prohibited pecuniary use,  if  sending those packets to
order a pizza  to share with a business client.
