“more”:
I wasn’t exactly clear on what point you were making. However:
By comparing smartphones to Chava, why bother with Muktzeh? After all, it’s only a siyag.
While Chava may have erred in that particular instance, Pirkei Avos does advise “VaAsu Siyag LaTorah”.
Chazal also say to be miod miod zahir in inyanim of arayos, whereas that lashon was not used by the Eitz HaDaas.
Again, I see their logic even if it’s not a universal standard.
