I agree with you pretty much, but with more and more tickets being listed for the reasons you state, and the demand seemingly not being there to pick up those listed tickets, it’s a concern in my opinion.
With regards to the “league stage” as we now call it for the Champions League, it should be an opportunity for the club to encourage families, people with kids to attend with reasonable prices, making it available to non match day members early on, etc. but they really don’t seem interested in doing things like that.
