There are a number of factors that contribute to mining vulnerabilities.
For example, presuming a miner is a meaningful contributor to the network,
they'll be using more electricity than their neighbors and will be easily
identifiable in the same way illegal grow-houses are identified by the
local power company working with authorities. A hacked or seized hosted
server is far easier to recover from than seized equipment. Its hard to see
how requiring a reasonably reliable internet connection is a particularly
high barrier to entry when compared to the other mining requirements, such
as funds to purchase ASICs, competitive electricity costs, reasonable
belief that equipment won't be stolen or seized, the technical knowledge
for setting up a p2pool node, etc.
