Well said, Jun.
Unfortunately, it takes courage to find your own aikido through determined practice under a teacher and then grow into your own style. The principle of 'SHU HA RI' is the traditional way of describing this process.
Many people want to set Ueshiba on a pedestal and give him "special powers" so they can idealize his aikido as the ultimate. It's then fairly easy to never have to take responsibility for the freedom of doing your own aikido.
Others want to do their own aikido before they have learned the principles and established the foundation which makes their own aikido real.
