Notes:

What I think each point is referencing:
"Media outlets have their own self-serving agendas": Almost anything with Aya and/or Hatate.
"The technology-dependent infrastructure that elevates us above beasts can just as easily become a prison": Wily Beast and Weakest Creature.
"True isolationism is unsustainable": The whole nature of Gensokyo is to isolate the youkai so they can continue to live.
"Everything has a role to play…": Double Dealing Character? Maybe?
I'm not really sure what the other 2 are on about.
