Proof that nobody exits besides me and I am the world

Now this may sound arrogant, or crazy, but bear with me.

Some facts:

• Subjectivity is inherently tied to the experience of reality.
• Subjectivity is a thing out there in the world, like everything.
• I have the subjectivity because I exist.
• Therefore, the reality IS my subjectivity, which IS me.

Now let's think about this for a moment:

FAQ:

1) What if there are other subjectivities out there?
If there were, they would be part of reality. And all reality exists through my subjectivity. So all those subjectivities are actually part of my subjectivity.

2) What if there is reality that is not subjective, but objective?
It is not possible to experience reality without a "point of view". This point of view IS the subjectivity. For example, if you did not exist, what would reality look like? There would be no reality.

Any more ideas, questions?
