Whether "groundless" is appropriate...
The internet definition of groundless = "not based on any good reason". And I really would want to know the original Greek word used? Don if you know?
I need to track where I read something about the view of deeming something as groundless -- after the fact or while thinking through/imagining (placing before the eyes) -- and then one sees that it 1) it causes a lot of pain and no pleasure, or 2) it is impossible to get.
For example: if a person said: "Oh how I wish I could go on a flight on Blue Origin, but it costs $1.25 million per passenger so I can't afford to do it." So then one would then reason about how this desire is not necessary for a happy life AND then replace that desire with something easier to get. Or another (more down to earth) example: if someone has very limited finances, but says "Oh it would be so nice to go to drive to a resort town on the ocean, but hotels are so expensive these days and I need to be careful about not spending away my limited savings." -- and then sees that the basic "deeper" human desire is for exploration (or for learning, experiencing, novelty, or relaxation) then finding something else such as exploring things and going to museums in one's own city, or finding a nice park with a river or lake.
This might be the kind of thing that we need to develop clear presentations on and this could eventually be part of a daily reader/guidebook -- or an "Epicurean Basic Training".
