It's a good point. What Robinson returning does is give them flexibility. They still
could draft a WR in the top 3 rounds. But they don't have to.
Forcing any draft pick at a specific position typically rarely works out. If the value falls to them, great. If not and they draft a WR in the 6th round or something then they're in a good place for 2024.
But to your point they would then enter 2025 with just (32-year old) Kupp and Nakua and then most likely be looking at needing to draft a WR in the top 2 rounds.
