Please don’t, the misunderstanding is common, and it just reinforces the point of the rebuttal. I’ve seen sooo many anti CP laws trying to be forced through congress, but most of it is just bullshit surveillance or drm stuff but it gets the support from people like you who (understandably) hear about the propagation of CP and support stopping it via those laws.
The only issue is that different cuts and styles can affect those objectively correct measurements. When you ask a guy what size jeans they wear, they most often will also remark what brand they prefer. It’s not really that they actually prefer it, but mostly that fits better than maybe another brand in the same size.
I usually carry around $30 with my cards, if I’m budgeting it can help make there be a limit as to what I can buy without having to rationalize my purchase to myself. Also, nice to have if needed, even if that isn’t everyday.
