" Instrument flying is quite difficult and can be dangerous, "
...................................
On the other hand if you were to start your training with all flying being done on instruments except the take off and landings using the IFR minimums of 200 foot ceiling and one half mile visibility as your base line. Instrument flying would be normal for you and all you would need after getting your PPL would be getting a VFR endorsement added to your license.
So conversley for a pilot having only IFR training and skills it would stand to reason that flying VFR would be difficult and could be dangerous.
