"No large gatherings" is not the same as "lock yourself in your toilet paper fort for two months."
And no, they're not going to say no groups of more than five people. First, it's not something that they can reasonably expect will happen and secondly, that's far below the point where they're worried about the virus being transmitted quickly.
Austria has banned gatherings of 5 or more.
Austrians have been uged to self-isolate, with police deployed to disperse groups of more than five in public.

The goal isn't to prevent the virus from being transmitted at all -- that's not something that can be reasonably hoped for -- but to slow it way down. Once you have people working from home and not going to restaurants or movie theaters, it will continue to spread, but slowly enough that, hopefully, hospitals won't ever have such a glut that they can't keep up. (Caveat: In some areas, all of these actions are too late and the hospitals are glutted. Kaiser hospitals in Oregon have just cancelled or postponed all surgeries not essential to saving someone's life in the near term because they need the beds.)
So a big problem is that this is growing 22%-33%
per day. And deaths lag measures to contain the virus by about 3 weeks.
1.22^20 is 45. 1.33^20 is 300.
For every death there are 5 people who are very sick and need 2-6 weeks of ICU, and if they don't get it, they have a very high chance of death.
So if you have 2 deaths/day today, and you lock things down, in 20 days you can have 90 to 600 deaths/day, and every day have 450 to 3000 people who need ICU beds for ~4 weeks.
If you "level" the number of infections, after 3 weeks you need 9000 to 60000 ICU beds in use to keep people alive.
Nobody has enough ICU beds to handle that for very long. So when you see that coming, extreme measures may be needed to prevent your hospital system from failing and needless deaths happening.
This is what is happening in Italy right now.
The first two cases of the new coronavirus (COVID-19) in Italy were recorded between the end of January and the beginning of February 2020.

Those are new diagnosed cases; and as Italy is mostly diagnosing serious cases (that need hospital support), those are new serious cases (with about a week delay since infection).
350 new deaths yesterday. Those are mostly people who got infected before the lockdown measures. Many only dead because Italy has an ICU shortage. The numbers keep growing.
The United States has about a third of the world’s coronavirus cases.

USA is 10 days behind Italy.
Here are Italians talking to themselves 10 days ago, telling themselves what they wished they knew then:
I hope that is sufficiently cited.
