When I'm out of saddle, a lot of times I'm hopping from one side to the other, the clips are keeping my feet on the pedals. Another way to analyze, without clips while trying to keep contact with the pedals all the time, both your feet are applying some pressure on the pedals. No matter how small that pressure is, it's working against the rotation at some point. With clips, even though the upstroke will not create much power unless your legs are freaks of nature, it will certainly not work against the downstroke on the other side. This is my non-expert understanding.
I switched to clipless long before I was a half decent cyclist. I wonder how difficult it is to spin fast without "clips". If I'm to ride as fast as I can under the same condition first with flat pedal and then with clipless, I'm sure I'll be faster with clipless.
Getting off the bike is no issue, it's second nature to me now. I did have a fall earlier this season but the result would have been the same with flat pedals.
