This seems like a completely arbitrary and absolutely biased place to draw a line. Why Bitcoin and not luxury cars or Hello Kitty backpacks? How about we shut down Six Flags and Disneyland?

This sounds very much like you've decided that you don't like Bitcoin (and that's fine, with good reasons) but you have rationalized it with an argument that is almost certainly inconsistent with the rest of your worldview. Bitcoin isn't any more bullshit than countless other systems/goods, the argument based on environmental externalities is a very weird reason to draw such an absolutist line given all the other (arguably) bullshit systems that incur the same costs.
