>Commodity futures are not for the supply of commodities.

This is a silly statement. Commodity producers absolutely do use futures markets to sell their product.

>More speculators usually leads to more liquidity and more accurate deals on loans.

More speculators also leads to more speculation which can lead to anywhere up to a complete disconnect of the price from anything to do with supply or demand.

Case in point: onion futures are illegal in the US https://en.wikipedia.org/wiki/Onion_Futures_Act
