Well – this seems to be based on the idea that a feature is selected because of usefulness. Remember that natural selection is an undirected process based on current and most supported understanding. We don’t have features in order to do something – we have them because they created or maintained a beneficial behavior. The fact we still have toes may be because they proved useful for the above or, in comparison with many of our close evolutionary relatives, they were at one point more similar to the dextrous examples of chimpanzees and didn’t retain their usefulness, and so were, not to imply any intent, selected out or down. The fact that we can use our toes and the structure of our feet to either appear larger, reach things otherwise out of reach, peer over things formerly too high, jump, and sneak shows the current benefits provided…but doesn’t say anything about whether they were developed to do any of the above. That implies, potentially, a little too much intent.
