Mate so much of what you said is so incredibly wrong.
Techically any switch can get banned, & yes patched switches are hackable, thats not new.
I also dont know how on earth your getting 600$ for unpatched either.
Unpatched switch tablets on Australian ebay can go for 250$-300 tablet only, and AUD is worth less than USD.
Also worth mentioning, patched switches FW 4.01 or below don’t require a modchip.
Finally hacking your switch doesn’t mean you will get banned, in fact if you have half a brain with the measures you take, you almost certainly won’t get banned.
