[MCU] How can beings, whose powers come from a single infinity stone like Wanda or Captain Marvel, compete with Thanos when he has 3+ stones

It doesn't really make sense to me. Their powers derive from a single stone so Thanos possessing that stone alone should make him at least equal. But he would have lost to Captain Marvel and Wanda while having multiple stones in his possession and clearly demonstrates that he knows how to use them so its obviously not a "they are more experienced with their abilities" kind of situation. Even if it were, tahz maybe could hold true against 1 or 2 stones, but with 3+ the raw power alone would negate all differences in skill.

Thanos just *has* the stones, while those people are *drawing on* on the stones. 

Apparently, the power difference between having a machine that manipulates the stones vs having the ability to innately use the stones power makes a big difference.
