Depends on how you interpret the “stop saving” part of the phrase. If it’s just for an iPhone sure, it’s definitely sarcasm. If it’s a comment about not saving money at all and just scraping by enough to sustain and argue philosophy, then there are a lot of people that would agree with the non-sarcastic take. The phrase would have been better replacing “saving for” with “coveting” or something that better disambiguates a statement against materialism from one supporting selfish financial recklessness.
