No, you're not. I just said this 4 times.
And you've been wrong, all 4 times. If all the ideas from the "Card Ideas" section automatically go straight into the game, then you'd be correct. As it stands, the Card Ideas section is here for discussion and the forging of a creative community, which is assisted by art from outside sources which we give CREDIT for. We're not using the cards for anything but discussion in and within the constraints of a SECTION in a FORUM.
I steal your money, buy a new TV, add a tag with "money by icybraker". Perfectly fine, right?
I steal your couch, and sit on it with some friends. I don't sell it. Perfectly fine, right?
If you want the card idea to be good, make the idea good. Taking copyrighted images never is needed.
Your metaphor has many holes in it. First of all, I don't have a couch, but that's not the point.
Second of all, as Bloodshadow elucidated, money is substantial. Feelings are not.
Third of all, my couch can only exist in one place at any one time. An image off the internet can be used by someone else, but you STILL HAVE IT.
Fourth of all, ideas and art go hand in hand. A play can be brilliantly written, amazingly witty, and beautifully dramatic, but if the audience only sees a curtain for the duration of the play, they WILL be bored. Sight stimulates thought.
