Obviously there is no reason to bother with vertical landings on a fully functional full-sized US aircraft carrier. This would be for other ships, clearings in jungles, and cleared-out parking lots.
You'd descend toward an area that has been cleared of debris and personal. It's not more absurd than flying toward a ship at 135 kts and expecting to grab a cable without crashing into things and people on deck. Compared to what we do on a CATOBAR ship, rocket-enabled descent is really tame and safe.
Vertical landing with the F-35 isn't exactly safe. This is the standard for comparison. Rockets can respond faster. This allows better stability and faster shut-down.
