If the engine section gets reused, the core tanks reach orbit and become habitats or printer ink, the upper stage gets refuelled aces style,and the fairings might as well be reused or integrated in a giant habitat payload,The SLS becomes into a dream rocket. And only a commercial company can push hard enough. Though it seems that it takes a private company with high ambitions, rather than a giant public corporate. That is simple wrong. There is no money to be made.This is not just Boeing involved. NG/ATK make the solids. AJR makes the SSMEs, MSFC makes payload fitting, Jacobs does the launch ops and a new contractor will do fairings. It can't be commercialized unless somebody is willing to take over all of these tasks. Guess what, nobody is. NASA isn't' going to have the money to fly it enough and there are no other users.Commercial operator can't contract with others? Since when?

Boeing looked at it, in the event SLS was cancelled by NASA (paid-for HLV, probably a deal over the billions Boeing would be owed in contract cancellations). They decided there wasn't enough profit in such a venture.
NASA sees itself as the "anchor tenant" of the launch system and procuring one crewed flight per year for the next decade or longer. Where appropriate, the agency said, industry will "market" the large launch vehicle to other customers, including the science community and other government and non-government entities.
NASA says it wants to transition ownership of rocket production and ground services to the private industry. In return, this private contractor should build and launch the SLS at a substantial savings of 50 percent or more off of the current industry "baseline per flight cost."

The RFI is for a privatization effort, not commercialization. Two different things.

If both Starship and SLS become operational, then what for what missions is SLS to be preferred for purely technical reasons? (not cost, political, legislative, or "SpaceX is evil" reasons).

(not cost, political, legislative, or "SpaceX is evil" reasons).Limiting Starship to official shown variants (cargo/tanker/crew) and excluding expendable missionsAnd SLS to officially shown variants (Orion/Orion+CMP/8.4m Cargo/10m Cargo)Some ideas:(1) Orion. Could starship be an alternative to Orion? Sure. Could a modified starship launch Orion? Perhaps. But Orion is designed to work with SLS and this would prefer SLS I'd cost was no issue. (2) Certain Space station module designs (for example to the gateway) can be cheaper/simpler/smaller/safer if they are designed without any propulsion or power generation systems. If they can hitch a ride with Orion as Co-manifested payloads, they can be delivered direct to station. Could starship be modified to deliver modules? Perhaps. But no shown variants are immediately capable IMO. (3) Certain high energy planetary missions. Starship is also capable of BEO launches, but the missions become more complex ( for example requiring refueling). If cost was no concern, many would prefer the less complex launcher. (4) payloads that are larger than 9m in diameter. What is larger than starship, but small enough for SLS? IDK. But if it existed it would prefer SLS's larger optional fairing. Could Starship be modified for larger payloads? Sure. But see premise. Sent from my Pixel 5a using Tapatalk

Sent from my Pixel 5a using Tapatalk1, 3, 4 is why I think there will be an expendable version of Starship, especially considering they're planning to fly several expendable missions from the start. For #2 you just need a space tug, it doesn't have to be provided by SpaceX, there're several commercial tugs/satellite servicing vehicles in development.
