Ownership is a legal right. You found/created it, so society gives you the right to rule about it's usage for a certain time. The same applies to physical objects. You own something, because society gives you the permission, not because you have the actual power to protect it with your own muscles. And there is nothing wrong with this concept; it encourages people to search and create, and prevents people from being abused by the strong and getting their findings stolen. Generally, this is beneficial for everyone and lets society moving forward and to higher levels of quality.
