That's not an issue in most of the world; I don't think any of my current cards have ever been swiped. However there are still plenty of transit tickets that use a magstripe, and having those wiped is super inconvenient.
Hotel keys are what comes to mind as the only cards that I still swipe. A year ago I checked into a hotel and went back out to the car to grab my stuff - when getting back in I learned that I had immediately wiped the magstrip by putting it in my phone pocket. Had to reroute right back to the front desk.
I was in vacation in greece and we had issues because seemingly the phones reset their magnetic keys, so we needed a new one daily until we were told to keep them in a different pocket.
I lost the ability to use a parking exit card (mag swipe) due to a having a magnet in my wallet a year ago.
