One reference in passing I found interesting was that dueling was becoming a popular way to solve problems, given access to backups and modern medical tech. Some melee weapons and single shot pistols would be weapons most habitats don't worry too much about. Here is an idea of mine: Given post scarcity economics and value of reputation, what if wagers involving reputation become attached to dueling? Instead of a lengthy trial and lots of red tape, why not duel the person who accused you of stealing their work? My idea is this. Certain hypercorp elites (or at least a few habitats) eventually make reputation-wager duels into a more organized form. The loser needs to be resleeved (normally) and has a loss of reputation, and winner gains a reputation boost from the wager. There is a risk of someone becoming too much of a skilled duelist and resolving all of their problems in the "arena," but perhaps some regulations may prevent too much reputation from being gained or wagered. Perhaps they may also use a separate reputation system for dueling ranking? It eventually becomes a cross between a conventional duel, Roman gladiator matches, and UFC. Perhaps some more sports-centric groups adopt the trend, making it more of a sport. They might throw in complications to the fight (like an obstacle course to navigate, uneven terrain to fight over, some crude combat drones to complicate the match, multiple fighters, etc.). Weapons would mainly be single shot weapons (perhaps disposable, prefabbed pistols and musket analogs with soft lead projectiles) and melee weapons. Combinations may also work (like a bayoneted musket, heavy pistol, etc.). Obviously, what is allowed to go into morphs would be regulated. This might mean a decent reason to have some free running/parkour, martial arts, and melee combat in a session. A PC's background might be a disgraced fighter for such events. Still, 'dueling' in this sense could be the extreme sport of transhumanity.
