You can turn anything argument inside out by attacking its axiomatic foundation. For example, if I give two people $1000 each as a gift I've favored them both equally, right? But suppose person A is not very materialistic and is completely satisfied with $1000 whereas person B doesn't think it's that much and only feels (say) 10% satisfied; if I know this in advance, wouldn't it have been more just to give person A only $100? But what if person B is just more selfish, or already has so much money that their threshold of satisfaction has escalated in proportion to their wealth? Should I considering the absolute utility of $1000 or the marginal utility to the receiver? And so on.
The problem with hyper-intellectualizing things is that it's like developing an autistic fixation on train schedules and making passionate observations about the 2nd derivative of punctuality metrics, but only on Wednesdays; it's not that the observations are wrong per se, but do they matter?
