Millions of dollars. The games active population doubled during the month Asmongold and other major streamers began streaming it, despite being in the midst of a major content drought.
The current population is now lower than during that Pre-EW content drought, indicating EW has a lower player retention rate than previous expansions.
The games normal-mode difficulty has not been consistent over its lifecycle, so these types of analogy's aren't great.
Coil raids were considered base difficulty at one time. Trials like Ravana, Sephirot and Titan had perma-death mechanics in normal mode. Eden Normal raids are often significantly more difficult than Alexander raids or Pandaemonium raids. Return to Ivalice is VASTLY more difficult than Void Ark, Nier or post-ARR CT. Yoshida indicated recently that the new 24 man series is more in line with Ivalice difficulty, which would mean the difficulty has increased from last expansion.
You lump yourself in with the people who are 'happily walking in the walking club', but you yourself were supporting the idea that certain trials should be made easier in another thread. It's a much more mixed issue, where the game could really go either way and you have people with different preferences tugging at both ends.
