Star Wars universe does have lasers of all scales and power levels.
Yet literally no one uses them well on a personal scale.
The Jedi (and Sith for that matter) imbue it with a power of magical stone, and then…use it as a saber.
To balance this stupidity, stormtroopers, clones and droids all use slow, non-continuous energy blasters. With actual lasers, they could insta-kill any Jedi, but they cannot, because otherwise the movie wouldn’t exist.
The OG trilogy was an interesting-enough drama with a vibrant setting, made groundbreaking by their special effects. Everything else in the franchise was made to sell toys, with maybe one or two exceptions. It’s not supposed to be taken seriously like that, I think…
