LFR was invented to prevent such human trafficking and raid gating which was in the hands of the GMs/RLs.
who are those GM/RL ? normal players that pay same fee as you ?
what you suggest is to bring in game dirty and corrupted real life politics tipical of human beings.
get ready to sit on the bench for hours or days while seeing your GM selected his friends to raid with him and eventually it will make them better geared which leave you on the bench even longer or without a guild wondering the forums for hours looking for a guild who will accept you with your out dated gear.
in other words - slavery, and slave masters thats what you are suggesting.
