Intellectual property are everywhere but it most people aren’t exactly aware of what it is and what it is for. It can be as an intangible asset of a company or an individual and it is valuable for those who owns it to be able to claim it as their own so that nobody else can just completely copy it off them since the intellectual property they have is their source of income. That is why intellectual properties can be protected since it is the company or the person that thought about it and had the idea about it is and might be the only people or group of people that might ever think about it.
The intellectual properties aren’t thought of and created for free after all, it takes a lot of effort to be able to create them.
For example, an artist is commissioning her art as a way to earn money. But then, somebody else uses her art, traces it then sells the traced art. That is very offensive for the artist since it is time consuming and uses a lot of effort to create. Art is usually expensive too depending on the materials used so the original artist would really be offended if their art is simply stolen from them, other people claiming their art as their own.
Even if the person used a lot of different images to trace and sell the art it would still be an issue of copyright from the images that are owned by other people or companies and franchises. Tracing and referencing is entirely different after all because tracing is simply drawing over it while referencing is all about thinking about your own art things like the posing and such then if you don’t know how to draw it that’s the time you should look for reference. You’re making an entirely new art not copying off or tracing something.
It has always been an issue on the internet about reposting art as well without permissions from the artist and this is also damaging for the artist’s part since they cannot be recognized at all despite the fact that it’s their art that they’ve put in themselves too to be able to create it and have a bit of their individuality.
