Are you questioning that the sun is a self-gravitating body? (now
*that* would be a case for crank.net). The virial theorem applies to
the sun like for any other structure held together by gravitation.
Even the corona is bound to the sun as you can calculate for yourself
from its temperature and the solar gravitation. Only some high energy
particles escape as the solar wind.

Isn't the solar wind just part of the corona? And what's the average
speed of a hydrogen ion at 10^6K?
