I have also examined the burn procedure with a hands and shoulders raised viewpoint. I think it would be better to treat it as a 'return to source'. Meaning, staked coins come from the burn pile first, before any new minting takes place.
Money does 'burn' to a certain degree. Money is lost or the banks destroy old bills and then print new bills to replace them, but that's not representable in a digital currency standpoint. Crypto wallets can be lost. I suppose some mechanism to introduce coins to compensate for those losses, even if eventually found and reactivated, could be coded in some way.
Just random thought befoe I run off for my day of labor.
