How on earth did you extrapolate those figures? The average time between testing positive and death is 14 days.
So look at the 151 deaths and compare that with the positive test number from 14 days ago - approx. 600.
That is 1 in 4.

Now look at the fact less than 3% of the NV population has even been tested. 1/3 of those were positive.

So if you just remove all the restrictions as you suggest then 1 in 12 people will die, not 1 in 50.

As for LV itself, it has the potential to be a way bigger hotspot than NY. Doesn't change the ratio of 1 in 12 but speeds up the transmission exponentially.

With the right restrictions and isolations there is a fair chance the percentage of the population that gets infected before a vaccine is readily available is only 20% max. Then the death rate becomes 1 in 60.
Take out the fact the stats say so far approx. 85% of deaths had serious underlying health conditions and may well have not lived to the vaccine time even if not infected. You may limit deaths caused by virus alone to 1 in 900.

You want to cull an extra 2% of your population to rescue the economy a few months early? The stronger the restrictions the better.
And before you compare the numbers with the UK, don't forget out population density is 8x the US.
