Let's have an example. Let's imagine this is about writing- another form of intellectual expression. Are you familiar with books by John Steinbeck, or maybe Henry David Thoreau? Those books have nothing in them to keep you from copying the stories and putting your name on the work. Yet- we don't hear of many known writers that are later 'found' to have been stealing work.
These books have no real protection. Especially in other countries. Yet, you don't hear England complaining that China wants to credit Wing Tsit Chan with writing Romeo and Juliet.
Consider the inspiration you have, from the wonderful works that other humans have shared. Things like literature, science, and perl- benefit from putting energy into looking forward into what can happen. Furthermore- I suggest the community will look out for you on some level.
