I would give all the monies to elon musk so he can build me a one man spacecraft. I'd bring a bunch of snacks with me and float in space until I die. When aliens find my body, they'd most likely use their alien technology to resurrect me and i'll give them the coordinates back to earth. I'd give them a sob story how as the ruler of earth I only wanted to help fellow earthlings but they banished me to space. With the help of the aliens and their tech, i'd come back and become the one true ruler of earth.
