That may be true but isn't necessarily true. I am referring to highly modularized code. Tight coupling doesnt mean that the module can't be reused, it just means the interaction between them is heavily utilized.
For example a vehicle class can make boats, cars, trucks, planes, etc. Some will be more tightly coupled than others (like cars would have more characteristics that we think of for a vehicle) but it doesn't mean that it's a bad thing as it can be used (and reused) by a plethora of organizations and applications (domain allowing).
Large systems with a small number of modules are absolutely a bad idea to have tightly coupled (this is a bad idea in general lol). But I see your point
