But the thing is, the general problem of packaging is a complicated system, and the current solution developed are there to solve those complications (which adds more complications unfortunately).

However, the article wasn't about this general problem of package management. It's a problem of somebody wanting to test out some code, and went down the rabbit hole without understanding what they're doing (not a slight at them - it's hard to know what to do).

Ideally, you don't go down that route, because testing out some code doesn't require solving the packaging problem.
