The point is for people to have digital backups their roms to play legally and to play roms on native hardware that will guarantee smooth playing. The cost is also a factor since the switch is ending very soon; a used switch oled, a cart with 7 years worth of “free” games would <=$300. Pretty cheap if one wants to start gaming without breaking the bank.
Adding on to say, yes the Steam Deck is cheaper and better when getting one at the new discount prices. It all depends on preference for emulation or running on original software. And most here would agree that Steam deck with emulation is preferred.
My definition for very soon is with-in 2-3 years. In my opinion, a lot the games that are coming out are mostly filler and Nintendo has a track record of doing so before going on to the next big console with the new big AAA titles.
