I think mission money coming out of a pool of tax money is a great idea to buffer quanta printing. It also gives NQ a means to really control inflation by giving tax money a multiplier (could be > or < 1 as needed) as it becomes the pool for missions.
Although I am a single account player, I support the idea of people paying for additional accounts. However, VRing alts to do missions will lead to the tax just being a redistribution of wealth from people playing the game to people using alts to VR missions. But I guess the finite pool of tax money to missions buffers that a little.
