Nope. That is an example, or illustration.
Why would you attempt to use such a terrible example which fails miserably at demonstrating your point? Are you willing to retract this example? B/c it doesn't, in any way, prove what you are attempting to say it does. There is simply no reason for thinking that hoarders (or alcoholics, or depressed people, or drug addicts) are such b/c of some "spiritual" deficiency. Such can be demonstrated quite easily by the fact that psychotherapy has helped people (including tons of non-Christians) to recover (without religion). "Spiritual" is not an explanation. It is a non-answer.
Yes, hoarders have a spiritual problem.
They are just one example of people with
spiritual problems. Drug abusers are another.
They are people with a deficiency in their lives
attempting to fill the void in their spirit.
Or mask the empty feeling with drugs.
