In large companies, these pointless mandates come down from higher-ups who are completely divorced from individual contributor reality - and are initially completely ignored by everyone below a certain level in the org chart. Ground-level HR doesn't want to enforce these orders, because they're measured on (inter alia) employee satisfaction. If the higher-ups don't go investigate, they won't find that their whims are being ignored, and life will go on - everyone remote, but the top brass in blissful ignorance.
What can upset this apple cart is either a nosy higher-up who actually follows up on his diktat "just because I want to see my monkeys dancing", or a surprise event that reveals that no warm bodies are, in fact, sitting in cubicles. For example (and this is not a theoretical example) a site might get a surprise visit from a third-party inspection team, and nobody is there to answer the door. This typically leads to a progressive tightening of rules after each incident. Again, basically everyone below a certain level in the company recognizes that this is meaningless nonsense, and complies to the absolute minimum degree possible, with a strong element of "don't ask, don't tell". I've observed this at multiple organizations.
The only case where followup/investigation is guaranteed from the get-go is where RTO is explicitly put in place to cause attrition. Attrition numbers are easy to see on a single slide of a PPT, and they're watched closely. If not enough people quit, there will be an investigation as to why not enough people have been made sufficiently unhappy to leave the company.
