ELI5: When a game's "code is lost" what stops a company from dumping/decompiling code from a disk or cartridge copy of the game for things like remakes and remasters?

Decompiling isn’t all that easy, and if it works at all you’re left with bare code that contains no notes about how anything is supposed to work.  Millions of lines of code that someone wrote years ago with no explanation about what they do or why.

While it’s theoretically possible to reverse engineer a program that way, it is much too time consuming to be practical for a product you’re trying to make money on.
