I'm an old guy (65) who rode with toe clips (and cleats) in the old days - training and racing in and around Los Angeles. The thing some of the folks posting don't seem to understand is that unless your foot is attached to the pedal in some way you will never be using a good deal of the power in your legs - which is kind of the point of actual bicycle cycling.
Toe clips are used with cleats - otherwise they are just a way of keep you foot from sliding off the front of the pedal, in which case straps are irrelevant. The straps held the cleat in place which effectively locked you into the pedal - exactly the same as the modern clip less pedal.
To me, clipless pedals were a revelation - probably the best advance in cycling I'd seen. With a small amount of practice getting in and out the pedals is just as automatic as removing your foot from a toe clip without a cleat.
When I'm climbing a steep hill out of the saddle, the clip less pedal is worth its weight in gold.
