Worst case is that the rubber deteriorates from rubbing against itself, the strut becomes looser, and trying to make that turn, you lose control and total your car.

I would drive it for a week at reduced speed, but nor for a month or two.

If you are a competent mechanic you can buy the part ($30) rent a spring compressor at your local auto parts store ($5) and then replace it yourself. It should take about 3-4 hours. Just be sure to put the whole front end up on jackstands otherwise you will have to fight with the swaybar links. It's cheap insurance and brings peace of mind.
