You don't understand, because you don't want to understand. It has been said by numerous people lots of times that the reason why this wouldn't be feasible is how the flashpoints are infinitely repeatable to obtain full rakata gear rather than through the traditional way of weekly operation attending. The reward already offered in HM LI is well in accordance with it's difficulty. Rakata Chestpiece is among the most difficult to obtain Rakata item in the game, and I know a lot of people who have even BH gear but no weapon, that Columi weapon given there is also quite often sought for. I am not even adding the pet and the mount, not to mention the 8 additional BH comms to your already 5.
So what? Rakata is no big deal now, and its implants/earpieces/relics can be obtained with daily com. Only SI/JC could not get their MH with strip out offhand weapon's mods.
And you get none of these(beside the pet) unless you beat Lorrick, but the 3 bosses share the same difficulty. Which means you get none of these after the hard work against LR-5 and Sav-Rak.
