If you scroll down on this forum you will find a thread titled "How many flat/platform riders are out there". There are different opinions about clipless, toe clips and flat pedals.

The OP seems to think that she has to use clipless pedals; Maybe they really are better for a trained professional, but maybe they aren't necessary for most riders. There are studies that show there is no real advantage to them. If someone thinks clipless is better, go that way. If someone isn't comfortable don't use them. Whatever one uses they'll get to where they are going.
