No, simply by way of an apology so as to provide an alternative viewpoint.
God's Kingdom is no false thing for it is the theme of the Bible . Daniel was not aware of 1914 CE but he was aware of the development of the World powers who would be replaced by the intervention of God's Kingdom as explained in Daniel 2.
The Bible says plainly so that the reader can readily grasp basic facts that the tree dream refers to the length of its being restrained as seven times and not seven years and that the reason for this divine act was so that Gode's rulership is supremed as expressed by the kingdom mentioned right from the beginning to the conclusion of the dream.
The dream centred around Neb's experience to make the point as part of a prophetic drama so he was banished from his throne for seven literal years, a fact that you do not accept anyway.
The interpretation of those seven times is done in harmony with sound exegesis drawing upon not only the book of Daniel but the OT and the NT.
Regarding your last question it is for you to make an account of this as it is you that insists that it has only a literal application so put up or shut up!!!
