I think this is part of the mindset the OP is criticizing.

Following that logic, a software cannot possibly be completed - It can be either in development or dead. Which would mean you either have a budget of time, money and resources for constant maintenance of your software - or you might not write that software at all. Repeat that for every new piece of software you want to write.

The problem is that this is impossible to do for hobbyist authors, so we would lose a large amount of free or open-source software currently available.
