There are a few important facts missing from your analysis.
1) Omicron, although less deadly than Delta, is significantly more spreadable.
2) Omicron can infect and be transmitted through vaccinated people--although they do suffer even milder symptoms.
3) The logic behind restrictions is to flatten the hospitalisations curve. Because of how infectious Omicron is, even if there is a lower likelihood that a COVID patient will need ICU, if the number of COVID patients is huge, then ICUs will still be overwhelmed.
This is why it matters if students spread Omicron unchecked to their families. To clarify, this doesn't disprove your conclusion, but if your argument doesn't take into account these facts then it's "facts losing the information war" just as much as everything else.
Gonna take a leap and say I'm getting down-voted due to lack of references? So here are some references:
(1) "A growing body of evidence indicates that the Omicron Covid variant is more likely to infect the throat than the lungs, which scientists believe may explain why it appears to be more infectious but less deadly than other versions of the virus." 2 Jan 2022. https://www.theguardian.com/world/2022/jan/02/new-studies-re...
(3) "Even if the disease is milder, rapid onslaught of the virus could overwhelm health care systems (doubling time of 2.5 days means 50X increase in 2 weeks)" 18 Dec 2021. WHO. https://youtu.be/ltXkJTSBeaE?t=675
