The value in the process is making a ratchet of ideas which is highly customized to building your own lines of thought or "associative trails" if you prefer Vannevar Bush's framing.
If your idea worked, then one could "simply" rely on Google's database and a variety of associated tools to act as your zettelkasten—Bob's your uncle and you're done! In practice, you'll find that this doesn't work well. You can experiment, but I think you'll find that your own limited choices of links will work far better than the infinite number of adjacent possible links that a digital system may create on your behalf. If you're already fighting information overload, you don't want to add link overload to your list of problems.
Put in a different light, it can be interesting to randomly flip a coin and go left on heads and right on tails to see where you might end up, particularly if you're unsure. But if you actively make your own choices, you're more likely to be happier with what you see along the way and where you end up.
