yes i understand what you are saying and understand that you feel i am probably contradicting myself!
What i am trying to get across is that one should be careful of over-attachment and over-identifying with the body (as well as mind and emotions).
A souls consciousness needs to stay in connection with the body for health and vitality and in order for the soul to fulfill the soul contract (ie what you came to earth to do as well as the karma you need to transmute)
The problem arises when people either abuse their bodies - ie drugs , drink unhealthy eating
or they completely reject their bodies and start living in their mind - in that case the consciousness lives in the mind, then the body doesnt get the necessary prana or chi (whatever you want to call) it and that leads to health problems.
It can be complicated for the mind to understand this , thats why sometimes it can be better to experience it.
I understand what you are saying about your body being useless and only dust, and you are right in a way the body will die.... but while you have it, you do bear some responsibility towards it because your divine consciousness created it as part of its mission.
I hope i have not confused you or offended you, i only serve to attempt enlighten people, some receive it graciously , some do not,i respect your free will,
