I see. Your claim that it it is entirely negative is fine to make without any support whereas my claim that there are some situations that could be positive (only one suffices) is not okay even when support has been given (any mine that is opened or distribution center that is opened employs speculation).

You are just making a bunch of claims with no support but “people I trust say so so the claims are true”. Now I really will bow out.

I am taking the null position here. That the speculation market doesn't help. If something isn't helping and is extracting value from the market its by definition detrimental. The onus is on you to provide the proof for positive positions, that the speculation market does help.

Nobody is forced to use the futures markets. The onus is on you to explain why it’s negative despite all of the sellers and buyers choosing to participate there.
