I used toe clips for many years; I never used the clipless system of attaching to the pedal. For the last couple of years I've been riding platforms like Grip Kings and the VO touring platforms with little spikes.. Maybe I lose a little power going up hills, but I really don't care; I'll be 79 nextmonth. Another reason I don't attach my feet is that there is a lot more traffic in my area, and I have to put my foot down a lot more often. not being attached seems safer:. perhaps my reactions are a fraction of a second slower. Grant Petersen has written afbout not being attached, and I agree with him. It is fine for some riders, but you can enjoy yourself just as much with your feet free.
