What crackdown? They half tried a few laws against concert/event tickets some years ago (no great effect really and more aimed at ticket touts which is already a thing) and at random times a few politicos might try a bill but nothing really gets passed, especially not for luxury goods.
So yeah it is legal and probably always will be for said luxury goods. Thus no breakups nor arrests and unlikely to be -- if you have something you can resell it and infringing upon that would be a breach of general consumer/human rights in many regards. Some retailers might try something technical as they presumably want the customers (they buy games and accessories after all) but that is all them. Only way the police might get involved is if dodgy credit cards or non fulfilment of orders was happening. I would be stunned if the police even did a "we hear you are scalping PS5s, maybe you want to find another town to be doing that in" type deal.
While I know you mean in case of someone confusing schooling establishment from shooting establishment (many of the same letters) I am still going to read that as lockdown (also known as lock in) for a pub
being drunk in school was either because drunk on playing field or could not be arsed with one particular Thursday afternoon so went and had some beers and played some games instead before returning for an ill advised last lesson/period
