Boosters are a zero sum game - currently there will always be another booster, and lots of people will always require a booster as not everyone gets boosted at once.
As for kids we are vaxxing them without knowing the real long term effects on them. Not to mention they are the least affected so again other than blatent fear no real gain.
As for RATs there are enough RATs for what we really need - sure there aren't enough RATs for all the covid hypocondriacs but they don't really need them.
