Yes, but Elon has now confirmed the unboxed line is 100% only for Robotaxi's. If Mexico will only be building unboxed vehicles then it will likely be building RT's only. If Mexico was going to build 3's, Y's, or CT's then there would be little reason to delay its construction, other than possibly waiting for interest rates to fall so demand increases.
Elon stated the "affordable car" will bring production up to 3 million EV's, utilizing unused capacity at current plants on current lines. He did not give a timeframe for that (other than starting in late 2024), so while 3,000,000 is 50% over 2,000,000, this production ramp could take place over many years, not the 50% CAGR we were expecting just one year ago.
Its okay to bang your head against a wall if you want to, but its also important to read exactly what Tesla and Elon are saying and witness what they are doing, rather than "fill in the blanks" with hope. Tesla is changing right now, as investors its important for us (IMHO) to analyze this with a disconnected POV rather than what we want or would like to see. Particularly without emotions clouding our judgements or rationale.
