Say again? You're suggesting that inputting a lat and long is somehow deceptive, inaccurate, or a lie?
Verify your coordinates and enter them. Not exactly rocket science, and pretty darn precise.
I spent years locating points in the middle of nowhere visually when responding to fires and other emergencies. When GPS became available, I began integrating that with LoRaN and other navigation to find the same coordinates. Inputting the coordinates for a fire could take us to a single burning tree in a thousand square miles of forest.
There's no need to try to lay in a point on a moving map first. If your coordinates are good, they're good. You should always verify them numerically, and look at a real map at the same time; see if your coordinates are where you think.
I've long suggested that VFR pilots, including non-instrument rated pilots, carry instrument charts, anyway. There's a lot of good information on those charts that can be of use. Where practicable, it's a good idea for pilots flying IFR to carry VFR charts, too. It's not always practicable, but it's a good idea.
There was a comment about joining and using airways. Not possible if the pilot holds an IMC rating rather than an IR, which was intimated in the first post.
You can't fly an airway or airway routing while operating VFR? No reason why one can't do it IFR, either.
