You're quite overestimating our capabilities as a species if you think that planning, developing, and launching a recovery mission in a few weeks would be even remotely feasible. Sure, we've known that the thing's up there all this time, so in the very counterfactual scenario where we had started thinking about a retrieval mission a few of years ago, and the Space Shuttle was still a thing, and someone was willing to foot the n-hundred-million-dollar bill, I guess? I don't think any nation on Earth currently has the hardware required to rendezvous with a random spacecraft in orbit and bring it down in one piece. The Shuttle was unique in that respect.
