> But to get to the Sun, you need to subtract 100% of Earth's orbital velocity.

Yeah, one would need to substract 100% of velocity if it wanted to land on a surface of the Sun safely, bringing the ship to a full stop. But why might one bother with the slowing down, if ship will just get melted by the heat of the Sun? You need just to rotate a vector of velocity by some clever gravity assist maneuver.

Not true. To even touch the surface of the Sun you need to subtract nearly all of the Earth's orbital velocity.

Parker Solar Probe, for example, did this with a series of gravity assists off of Venus.
