Low myopia may cause enough blurring of vision to some people, and if there is desire to improve eyesight and reduce dependence on glasses, there is no reason to object to seeking laser eye correction, as long as you know your choices.
I once treated a patient with myopia as low as 50 degrees in combination with the same amount of astigmatism. The patient's eyesight improved by one line and it was a happy ending for the patient.
Some people suffer from "night myopia" when the degree seem to increase at night in dark places, due to the natural pupil dilation under such lighting conditions. So what is low power may actually be somewhat higher when tested in different conditions.
You may want to ask yourself about what you hope to achieve with regards to your eyesight.
One avid football player I treated years ago was already 41 year old when he had LASIK done for his low myopia (about 150 degrees). His aim at that time was to improve his game as he got very fed up with glasses and contacts by then. I counseled him fully regarding the pros and cons of LASIK in his situation. He knew what he was doing, got his wish and was much happier on the football field.
Hope this helps!
