To put in context the UK has 8.8 million people over 70 years old. Overall 15 million people in the UK have longterm health problems.
There are also many people who are live-in carers,ie,7 million. That means lots of old people are living with younger people and the latter have to self isolate too,as they can spread the illness to older folk. Lots of households in the UK are multi-generational. 1.8 million of the 9.6 million households in the UK are multi-generational.
Even if people go "back to work" a huge number of the population can't go back to work in a normal way and will need to self-isolate or reduce movements significantly. That includes whole households with older folk or younger people with health problems. So around probably 10~20million people I estimate,maybe more.
Also if anyone in a household gets ill,they will need to self isolate too.
So for a few weeks of isolation and restriction of movements,people are moaning,when literally EVERY other country in the world is doing it - even poor third world countries which don't have much social care.You are getting paid by the government for the period of the lockdown. It is being done to flatten the curve.
If a communist government quarantined nearly 70 million people,and restricted movement of nearly 700~800 million more people,it tells you something. If poor third world countries are doing it its telling you they are not taking it lightly.
Everyone in this thread is in the same position as everyone on the whole planet.
If you are not living with someone old/vulnerable in the first place,count yourself very lucky,ie,in a few weeks when restrictions pass,you can probably go out to work,etc. The government won't be locking down all the people for months as it can't afford it anyway. No government can.
Even at current levels NHS staff are starting to get infected at alarming rates. 100s of people working for Great Ormond Street hospital are infected and can't go to work as an example. If we started loosing medical personal to illness,things will regress,especially if their whole household has to self isolate too.
The slow response of our government,ignoring offers of test kits,ventilators,etc means we need to lock down longer than normal.
More ventilators and test kits earlier,would mean our healthcare system would reach saturation point slower. More PPE would have meant less medical staff would get infected. This is why we need to lockdown,to stop overwhelming the healthcare system. Remember the NHS has to treat not only Covid19 patients but all of those 15 million young and old people with longterm health problems. Saturation of the medical system also affects everyone of those 15 million people too.
If a Tory government and people such as Trump/Republicans are now increasingly locking down things,it tells you it is not a joke. These are parties of "business" so it is telling to me they are using these measures.
Edit!!
Also the predicted peak is in a week to 10 days for us,so if anything its important people try and stick to their self isolation as well as possible for everyone's sake.
The quicker we can manage the numbers,the quicker we can start going back to some degree of normal.
