This all comes down to risk tolerance and our society seems obssessed with eliminating all risk. There are some occasions in life when you have to take a reasonable set (not an excessive set) of precautions and then cross your fingers and hope like hell nothing unexpected happens. I can't think of a better example of such an occasion than a first solo.
You can't eliminate all risk and if you're the type who wants to do so and lies awake at night worrying to excess about the myriad things which might just happen, you shouldn't be flying an aircraft.
