You're right, reading it back it is illogical. The point I was trying to get across is, anywhere in the world, those who do business have to pay taxes on their profits. There is the odd exception, the odd discount, but they are the exception - not the rule.
Amazon sellers pay tax on their profits, online traders on daraz should pay tax on their profits. If people think that paying tax makes their business uneconomical and it's better for them to return to the small market they have access to using cash only - good for them, let them do that. Most people doing business will still be better off even after paying taxes, because e-commerce platforms offer them such a larger marketplace.
I don't think they need to tax free sweetner anymore. Daraz have a vested interest in campaigning for one of course.
