The idea o a risk budget is very simple to understand, yes - and i cannot understand why it isn't made MUCH clearer in all the publicity around Covid.
Everything is a balance of risks. Some things which we agree as a society are essential - education, work, healthcare - are 'big ticket' items in our overall risk budget. As a rweasult, we have to reduce our expenditure of risk on any non-essentialacticvities to keep the whole thing within bounds.
It's like having a menu, and £10 to spend. Just because there are a whole list of dishes at £7.99, you can't have the whole menu, you have to choose just one of them. And once you've spent that £7.99, you only have a couple of pounds left, so you are very limited in what else you can choose.
