Got to be careful though as it is all about balance. You may want the network to get stronger and one way to do that is to think about how other may leverage your content/kinds. You don’t want to just ignore outright the good work done by others and re-invent the wheel (but make it so it only fits on one vehicle). 

It takes a certain level of experience as well with the network to make the statements you have made (valid though they are). New folks (self included) may not be so confident, which is where having direction from NIP helps.
