I agree, and I recall Hartzell posting, that while foreign spouses do not need work permits, certain jobs require other permits or licenses and you would have to deal with that. (though I'm not sure all my neighborhood vendors have permits)
On the other point made above, The Taipei Times letter by Mr. Lick does point out that there is a difference between the letter of the law, and what some legislator said verbally while the law was being debated. And further that such confusion, and dependence on phase-of-the-moon, creates doubt in the mind of employers. He further states that this is no idle doubt, but that in fact employers remain liable and fine-able. I would go so far as to suggest that the legislature deliberately created vague legislation in an attempt to palliate both sides.
I will look for the other threads, but FWIW my current take is that Mr. Lick is right, I still don't see any explicit written article exempting me (a foreign spouse) from article 46.
Perhaps some people have real world examples from the 2 years since my putative emancipation.
