Energy is conserved – you can’t buy additional kinetic energy by adding inert mass.
kinetic energy, E[k] = .5 mv²; so with constant E[k], if you double the m leaving the nozzle, then v is necessarily reduced (factor .707). but under conservation of momentum, mv has therefore increased by 1.414. so adding inert mass increases thrust, but costs a lot more propellant.
