We got it. You've been repeating your point for 34 pages. Stay home. Well, the whole world is staying home. Now what? What is Greece doing now to get the tourists back? When are the Germans coming back to sip their ouzo and cafe? What should the US do? The rest of the world?
Now what: keep people home until the conditions are there that allow slow reopening. Several European countries are already slowly coming back to life, like in Austria, Denmark, Norway, Poland, Check Republic, Spain, and Italy. Such decisions always carry a risk, so it is better to listen to the specialists and continue to implement safety measures.
Now what: we get ready to face the economic crisis. Portugal will have a drop of the GDP of 8%, the highest in 100 years. Other countries will farebetter, others worse. But all will suffer. Estimate is that Portugalwill go back to 2019 results in 2021.
Getting tourists back: like Greece, Portugal has a lot of income from tourism. We will face a drop no doubt, but we started getting ready already:
https://econews.pt/2020/03/22/coronavirus-turismo-de-portugal-launches-campaign-this-is-the-time-to-stop/Right now there is another campaign to convince portuguese to do tourism in Portugal. A win-win situation, as in Greece, because for at least 1 year no one will feel like taking avacation abroad.
What should the US do: what has been shown to work in other countries, in terms of the science aspect. Other parts are OT.
Rest of the World: as above.
Bottom line: whatever measures are taken, there is a risk associated with them. Unfortunately, risk management is something that is often not well understood.
