I've always thought the same about the Watchtower teleport technology, alien tech etc but they put that in. I mean Batman can now teleport anywhere anytime and has access to a motherbox? It does kind of take away from the Dark Knight image.
Robin: "Hey Batman. Why don't we all build flight rings like those Legion guys were wearing?"
Black Canary: "Yes. Imagine the extra lives we could save - including our own the the next time we fall off a building during a fight or our team aircraft gets shot down."
Batman: "No. It would not look cool like running and jumping across rooftops. It would reduce your interest as a street level character. Robin - what would you ever need that grappling hook I gave you for if you had a flight ring? We just wouldn't be as impressive. It isn't all about saving lives or common sense. I'm sorry."
Robin: "OK. Come on Canary let's teleport back down to earth from our super high-tech Watchtower on the moon."
As for being 31st century tech... I think that having seen them in action on the legionaires they could come up with something similar by making use of their vault of Kryptonian, New God, Martian, alien tech etc. They've managed stuff far more complex than flight rings.
But yeah, I guess looking cool and character interest has to come before common sense or saving lives within the confines of the story.
