I'd recommend against trying to memorize Vim keybindings by position.
1. If you want to learn a non-QWERTY layout (e.g. Dvorak or Colemak), you're going to have trouble. (Although some users to try and go to the effort of remapping to suit the layout).
2. Similarly, you might also have trouble if you get a fancy keyboard that doesn't use a row-stagger, like a kinesis, moonlander, crkbd etc.
3. Many of vim's keybindings accreted mnemonically in the first place. There's often a mnemonic explanation or back-explanation for every single keybind. Many people communicate with them ("just yank those four lines"), and they form a sort of vocabulary to the "language" of vim normal and visual modes.
