> * What exactly is the problem with tight coupling?*

As Joel Spolsky put it: ”the cost of software is the cost of its coupling”.

More specifically the cost of making changes when “if I change this thing I have to change that thing”. But if there’s no attention paid to coupling, then it’s not just the two things you gave to change, but “if I change this thing I have to change those 40 things”.
