Are people really 'trading' these things? That seems like a bit of a stretch. I'm having a hard time imagining somebody justifying flying more/further because they aren't using plastic straws in their day-to-day life. Surely we can work to improve the world on multiple fronts at a time, and if single-use plastics present themselves as both unsustainable long-term and a low-hanging fruit (compared with air travel) in terms of sourcing replacements, then it's reasonable that people would seek to make that small change independent of what is happening in the rest of their lives. I find this trend of slapping "virtue signalling" on all but the most lofty goals to be a bit disingenuous. It must assume that there is one section of society that is empowered to make all of these changes and that by choosing to pursue single use plastics they suffer the opportunity cost of not developing an alternative means of rapid transport or improved environmental law enforcement. A single-use-plastic tax which truly takes into consideration the cost of enforcement / cost to the environment and landfill / depletion of a finite resource would have the same effect, sure. I'm not convinced it would escape the "virtue signalling" label, though.
