Tesla's aren't different than any other car. If you keep touching the door, it will wind up with scratches. If this is your first car that you really baby, then yeah, do PPF. Or just accept that your daily driver will show wear over time. Do you remember back when cars had keys to enter? Talk about scratch city!
Personally, I'd weigh the cost of full car PPF and ceramic vs doing a repaint/wrap down the road. I went with front/partial PPF (and glad I'm did) and ceramic elsewhere. This was already close to 2k.
