If you don't ever need to know or maintain the code, sure, it's not your code, you don't own it, in fact the code is disposable. For something like POC, where I don't care how it's done, I just want to see if it can be done - I've done it myself. Then if real code is needed, you throw the disposable one out or rewrite it completely. That's fine. But if it's a long term project, somebody needs to own it.
