I have an argument/idea against the whole matrix theory and......?

You are uming that the illusion was created by a conscious being, whose goal it is to trick you into believing that the illusion is real. Solipsism does not require that there be a creator for the illusion, and it doesn't characterize the illusion as a trick or deception. The creator of such an illusion would not have wanted us to question whether it was real, but if the illusion is just the way things are (was not created by someone for a purpose, it just is), then there is no creator to want to prevent us from questioning it.
