The problem in life in general and in this case in particular, there is little correlation between genius and common sense. Some of the most brilliant people I have ever known, you would not trust to tie their own shoelaces.
Such it is with the recommendations given to our government and course of action followed thus far.
The theory might suggest that allowing people to get infected - which is what we have been doing - get them treated and back out into the community so as to start to build up herd immunity, might have some possible legs.
But common sense says it's far too risky and based upon many assumptions which may be invalid. If these assumptions are wrong, then the entire strategy is flawed and many, many people die needlessly. The principle dodgy assumptions are these;
1. That draconian measures later on, will be able to stop the NHS being swamped. Given that Italy has twice the ICU capacity we have, and it has been completely overwhelmed, this is surely questionable. The common sense way to minimise the risk of the NHS being overwhelmed, would have been to limit the numbers to the greatest extent possible *before* significant exponential rise. We have not done this. Some of our inactions - like allowing unchecked incoming flights from Italy and Spain for example, have been wreckkess to the point of negligence IMO. And now have tens of thousands of infected citizens, soon to be hundreds of thousands. Many of them are going to get sick. The Tsunami is coming now.
2. That people cannot catch it twice. Who knows?
3. That all other options are ineffective and that "we'll all be catching it anyway". China saw an immediate drop in new cases the moment they implemented the shut down. New cases have now stopped. Similar in northern Italy. People say it will start up again as they get back to normal. But will it?
4. That people will get tired of draconian measures and compliance will fall over time.. Seems to me compliance is worse than it could be because of the governments "relaxed" approach. Also seems to me that people will be pretty disciplined when they see large numbers dying.
If any of the above underpinning assumptions by the government advisers are wrong, then we've chosen the wrong path and will have caused many to die unnecessarily.
