This is true. No one has ever gone blind from LASIK, but personally, I value my vision over (almost) everything, and losing it is a chance I don't want to take.
I absolutely agree with you which is why I'm considering getting the surgery. I experience a large amount of anxiety around traveling and losing access to my contacts or glasses. Also, what if someone breaks into my house in the middle of the night? "Excuse me Mr Burglar, let me put on my glasses before we wrestle."
