Indeed haha. But look at the situation of the comment. I had an immediate problem that I wanted solved that day (to prepare for that night). I thought about how I can block light and the only thing that came to mind was a black bag. It worked amazingly well and I guess it ended up being a top comment because it's something everyone can try with minimal effort / investment. Now that I know it's possible to block out so much light, I will upgrade the trash bag to something less ridiculous looking. Think of the black bag as whipping up a proof of concept that ended up being quite effective. Switching it to black out curtains is the refactor. That sure beats not taking any action on the first day, ordering curtains without even knowing what to get and if it would work and then having to wait for shipping. The trash bag isn't a question of being cheap. It's being pragmatic.
