"a bouy can hide behind a mast.."
Without a GPS on board, piloting at night can be a challenge too. Especially if the lights on shore are many and make it difficult to spot a lighted channel marker or bouy.
It seems common to read about "old salts" complaining about GPS dependent sailors, and conversely, the push back from those same sailors who use GPS exclusively.
Coming from a background of using the "Old School" methods, it is natural to want to retain the methods and techniques and knowledge and practice the skills we learned earlier.
The GPS gives sailors now such an easy, instant, and accurate answer to "Where AM I NOW?"
That certainty of "I am here or within 15 meters of here on the chart plotter position"
sure beats "According to my calculations and sights and plotting, I think I might be here, I think, yes, I am pretty sure I am about here."
In comparison, the "Old School
Way" can seem like using two sticks to start a fire.
