Earlier quoted context omitted.
You do realise not everyone has $500 to spare? For some people the distinction matters a lot. It’s the same reason some people with high end phones pay a larger monthly phone bill. They want a phone they cannot afford to buy so they pay in instalments as part of their mobile contract. So yes, it absolutely does matter to a lot of people.
It makes a huge difference to whether people buy it. It does not make a difference as a measure of "how much carbon does it release when they buy it", which is the question being debated in this thread.
That was discussed elsewhere in this thread. This discussion in this fork is very specifically about monitory costs.
Hence all the dollar signs. ;)
