If you can swing a bat you can swing a sword
You don’t need to be a master swordsman to swing a sword or bladed weapons in general. Again franky, pica, queen, kizaru, etc
Two of them use lasers, one of them wasn't even capable of applying haki to his sword, and Pica was a swordsman.
Now you're going for absurd examples of basic swordsmanship but earlier you were going for stuff like:
- Nightmare Luffy (actual sword skills)
- Ikoku Sovereignty (actual sword technique)
Luffy may some day hit an opponent with the blade of a sword, but he won't do neither of those things. And he already failed to use the blade of a sword just last arc when he actually wielded an important graded sword against some opponents, so even just hitting with the blade is farfetched as of now.
