Ideas, or "ideal objects" are not scarce in the economic sense. Wood is scarce because you and I can't use the same wood at the same time. A story, song, piece of software (etc) are not scarce because you and I can use them at the same time.
Time is scarce. Yet somehow you feel that you have the right to mine.
Time is not scarce in the economic sense, in fact it doesn't make sense to say that you and I "can't use the same time" or "can use the same time". I did not force you to share your ideas, you did it of your own volition. You have made no argument that you have the right to control the use of your ideas after you share them.
If I felt I had a right to your time, I would make you my slave or take your possessions.
