Jethro gave human advice, not God's wisdom.
Men who were to lead the nation were to be spirit filled (Nu.11:25) as were those who are to lead the local church (Acts 6:3).
Natural ability (as espoused by Jethro) is of little concern to God.
And your point is?
Says who?
You made some interesting, and controversial, arguments. Your blanket statements condemning Moses appointing men to share the workload, stating that Moses was wrong and that he never sought the Lord's guidance in that (implying that large churches are bad because the pastor doesn't recall the names of every attendee by sight) - yet you provided not a single scripture reference to support your arguments. Do you have any, or are you just speculating based upon your own rationale/human reason?
