I think your post was perfectly fine, for what it's worth.
It's a complicated issue. On the one hand, there is no ethical consumption under capitalism yadda yadda yadda, but on the other, it's perfectly normal for people to at least try to make the best out of an imperfect situation and find an acceptable solution that works for them. This isn't a clear-cut issue as with single-use plastics.
Personally, I still prefer physical when I have the choice and I even buy CDs on the rare occasion I can find one that interests me (usually a game soundtrack ), but I also find it hard to argue with Stan when he mentions the environmental impact of doing so. The way I rationalize it is that I try to do what I can on the big stuff while also allowing myself a small margin of error on the smaller stuff, such as physical game cases. This isn't a zero-sum game of course which means my solution is far from perfect, but it works for me.
The other issue I have with reducing everything to a matter of personal choice is that we don't live in any kind of libertarian utopia in which regulations and/or appeals to responsibility are inherently transgressive. If somebody has reason to believe that a certain course of action would be preferable, then it makes perfect sense for them to voice their concerns because it's by talking things out and finding compromises that we can find long-term solutions. You made a political argument and that is inherently based on the premise that what someone does usually ends up affecting somebody else, or in some cases, all of us. In this case, there is truth to the idea that digital storefronts are acting as predatory middlemen who exploit smaller creators and lead to bad consumption habits, not to mention the erosion of consumer rights you mentioned. But there is also some truth to the notion that digital media offers a higher degree of convenience at a mere fraction of the environmental cost.
Sorry for going off-topic or if I'm crossing a line again, I just thought this was an important point worth expanding on.
