No I am fully aware it is fully guaranteed. Let us go thru this again.
Aaron Rodgers contract and salary cap details, full contract breakdowns, salaries, signing bonus, roster bonus, dead money, and valuations.

1. His retiring is breaching the contract. This is why the Pack would be allowed to recoup all signing/option bonuses for years he did not fulfill the contract. You should know this as that is precisely what the Lions did when Sanders and CJ retired. Both had to pay back SB. So looking above that is over 40,313,568 that the Packers would be able to recover for 2023-2026 and in doing so they would get salary cap relief. So it would be a stupid game for Rodgers to play as he would then need to come up with 40.3m to pay it off just to then unretire.
2. If the Packers cut him, yes they would lose his rights but it would also mean Rodgers loses not only the 40.3m in SB that he could be forced to return but also the 58.3m in guaranteed option bonus. So he would be walking away from 98.3m that he would otherwise be guaranteed. There is no concept in contract law or the CBA whereby you can breach the contract but still force the other party to uphold the guarantees. That would the Packers choice not his. We know this because that is what the Packers did with Favre when Favre retired. They cut him while retired and when he came back he was a FA and signed with Minny. So that is a dangerous gamble for him to make.
3. Now let's say they want to retain his rights so they don't want to cut him. Knowing the games Rodgers plays, I would be shocked if they didn't have a clause in the contract that effectively voided the guarantees upon retirement. Teams have clauses like this all the time to guard against players being shady. So it is possible all guarantees void and then when Rodgers comes back the contract is an entirely unguaranteed one which would still transfer over to whoever traded for him. Here is an overthep article explaining the retirement is a standard condition that voids guarantees.
Teams that negotiate guarantees for players also negotiate scenarios in which the guarantees will void. Though these vary team by team there are some pretty standard void mechanisms that are used across the board. Such mechanisms include non football injury caused by performing dangerous activities such as sky diving, suspensions for personal conduct, steroid, drugs, or conduct detrimental to the team, incarceration, holding out, retirement, and doing something to undermine the team.

Now maybe the Pack are an utterly stupid franchise and neglected to include these void clauses but I doubt it. So no I think it is you that is confused.
