There's more to it than wordplay, but it's reasonable to argue that a lot of consists of building castles in the air, ie elaborating a theoretical system in a rigorous and consistent way but where your beginning axioms are kind of arbitrary, or depend on balancing considerations that are fundamentally unmeasurable.
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?
