If you designed Legion the same way, the event would instantaneously have a shelf life. Imagine if you could buy every single Limbus drop via Ancient Beastcoins and never have to zone into the area again. Imagine if you could buy every single +2 item in Abyssea with cruor. Bam, dead events walking.
MMO devs have to have some way of ensuring people actually do the content and fight the toughest monsters (e.g., WoW raids). Moreover, the events they design need longevity. It would be nice if all MMO items were obtained through points, but this just isn't realistic. Imagine, if you will, a scenario in Legion where people discover a way to farm a few smaller mobs ad nauseum and amass Legion points hand over fist. The event would be DOA. Anybody who enters would just farm that same mob over and over and nobody would touch the tougher bosses (e.g., Paramount Botulus Rex).
While in theory there is nothing wrong with being able to work towards everything you want, and not having to rely on building your own groups/LS or finding a LS with honest leadership, in practice what you are really asking for is a console RPG, not an MMO.
