[Star wars] What is preventing me to make a light saber with a really really long blade?

They didn't weigh and that massive range it's a huge advantatge.

There's nothing stopping what you're talking about. However, the Jedi specifically took steps to make sure people couldn't figure that out after a Jedi named Oo'b engineered a sniper lightsaber that could create a hundred-yard beam for a split second. They thought it was a perversion of what lightsabers are for, since you can basically only use that for killing as opposed to blocking, cutting through doors and the host of other non-lethal functions.
