Whoever has firsthand experience running into to rocks and reefs with a sailboat, raise your hand...
It depends on where you sail. In and around some venues running aground is a very regular accordance. The Chesapeake would be one example where anyone sailing a keel boat will learn to run aground and get off. Other area of the Gulf Coast also have issues for any deep draft vessels. All of the Bahamas have issues.... You will also find a lot of hard rock in Maine.
