Ten so that you can get rich. True / False

Hello Rabbi
It is simply a pleasure to hear your opinions on a variety of different topics, and no less so, and your ability to clearly decide a position, simply fascinating. As a Moroccan Baba, I am shocked (albeit a positive shock)
Regarding "Ten to Get Rich" I doubt it and statistics #24 or #25 I don't remember exactly, you claim if I understood correctly that it is simply not true. And you also came to the conclusion that it should also be published and said that it is not true (to people who are willing to listen)
Let's assume we accept your position that it is indeed not true. I'm asking about the point "that it is not true." After all, who knows that it is clear to you where we will go with this approach? We will begin to filter out what we think is true – rationally – from the Talmud and what is not. And after the Talmud, it comes to the Bible, etc…. Exactly what we are fighting against the Reformers…
What's wrong with leaving it as an unclear point (-the tithe-) and saying it's unclear? – By the way, it's really not clear to me, at least – because you haven't proven that it's not true – what's the advantage of actually saying it's not true? This is something that comes up quite frequently in your lessons, why isn't there much room for doubt or for things that don't work out for you/us as rationalists?
Thank you very much.
