Are you saying that such countries are merely postponing the inevitable? Any data on that?
Most countries have done too little too late, they allowed initial early spread when there were few cases and the growth seemed slow, but it's exponential so by the time people realize it is a problem, the time you could have done something about it was 2-3 weeks earlier.
It's a bit like "what's the best time to plant an Oak tree"? The best time is 20 years ago and the next best time is right now.
I don't think you can come up with any scenario where the countries that have had a lot of deaths would have had fewer if people hadn't tried to limit the spread at some point.
I do think a vaccine will be available for this virus within a couple of months due to the fact there are an enormous amount of clinical institutions that are working on a vaccine right now, dramatically more so than any other contagious virus to date.
Lots of vaccines fail clinical trials - not all are dangerous, they may just be ineffective. There's a reason the process takes as long as it does and you can't make a baby in a month, even if you group 9 women together (although I'm willing to take part in any research, LOL).
We hope there will be a vaccine and it will be soon, but there's no way we can confidently say it'll be here with a couple of months.
How, exactly, will testing be the answer?
The quicker and easier it is to test people, the easier it is to stop the spread - instead of having someone going round inadvertently spreading it, you can prevent it. That helps lower the R0, or the rate that people are infected. If you get it below the higher number, which I think is 3 (?) then it slows the spread. If you get it below 1 then it dies out (fewer people are catching it than have it at that point).
People will have more confidence to go to work etc... if widespread and easy testing is available but lowering the rate is the key benefit. Testing allows for targeted isolation rather than "isolate everyone because we can't know who does and doesn't have it".
It looks as if you can physically and mechanically remove it from your skin by washing. However, it then proceeds into the drain and eventually the sewage system. If it's not live, then what mechanism makes it inert?
I believe that the soap breaks down the structure of the virus. It happens naturally as it is exposed to the sun, elements etc... and the time it can be active on different surfaces varies (up to days on some).
It's interesting that copper has natural anti-viral qualities and was what used to be used on hospital doors. That piece of genius seems to have been forgotten and now we have surfaces perfect for keeping it infectious - brilliant! Always use your elbow or knuckles to open or push things - it's all about limiting the chance that you touch something that has the virus on it and then touch your face afterward.
If you have a delivery or go shopping, you can either wipe things down with disinfectant or you can just leave it for a few days, or both (belt-and-braces).
If you are getting a meal delivery that is in something that the virus can live on the surface of (e.g. plastic containers), then empty the food onto a plate, then dispose of the packaging and wash your hands (the full 20 sec thorough deal) before eating and that should be OK.
Just try to be methodical and think about the order that you touch things in and that should dramatically cut down the chance of picking something up even if it happens to be there.
Does spraying public places help -- and how -- if it's not alive?
I think that's all for show. Unfortunately, some people need to be "scared" into accepting rules such as social distancing - it's likely for them.
