VM- are you trying to deny that sometimes people have every intention of staying frum but are nonetheless tempted by the yeitzer harah to go off the derech, or at the very least decrease the level of their frumkite?
I think it is decidedly against chazal’s ideas of temptation and self control to think that only people who are “looking to run away” are affected negatively by things.
There are lots of things that could be good “tools” but we nevertheless stay away from because of the risk that things wont work out the way we want.
On another lever, many would argue that even if you are right (and it is a function of wanting to be frum or not, but you are wrong), allowing those who want to stay frum to use the “tool” properly, gives cover to those who want to use the “tool” improperly to get away with it. Kol Yisroel Areivim Zeh Lazeh, sometimes even those of us who can handle using certain tools have to refrain in order to make sure others dont have problems.
