In comparison to other disposal methods yes.

Because the earth is moving very fast sideways compared to the sun (orbiting) so anything we launch has the same has the same velocity and would probably end up orbiting the sun too

I have mixed feelings about him. I have listened to a lot of different interviews with him and I truly believe that he believes in everything he says and does 100%, which to me does count for something. The problem is, I think he's completely delusional and his proposed solutions to America's problems are just doubling down on failed Clinton era policies without examining what is actually wrong with the system and society that created Trump in the first place. His proposed cause for the collapse of neoliberalism is that we just didn't do it right and need to just do neoliberalism harder. It's like he just mainlined episodes of the West Wing instead of doing any kind of introspection.

Cory Booker, unlike most politicians in general, does seem to be someone who actually has a set of guiding principles that he follows. The problem is that those principles are incredibly misguided. In a pre-Trump world I probably would have loved someone like Cory Booker as president but the world has changed and it's become a lot clearer that neoliberalism is a failed ideology that just leads to more inequality.
