"Spanish flu death estimates range between 30-100 million people. That's the cost of herd immunity. Let's take an average and say 50 million. There are 4.3 times the population in the world today compared to 1918, which would give a death toll well over 200 million people (and that's using 50 mill as the starting point - it could have been a lot more). Don't you think there are smarter ways to combat this virus?"

Well, if you want smarter ways to combat the virus, you need to be a lot smarter at understanding the numbers.

For starters, the Spanish flu struck at the end of World War One, a period when resources - medical, nutritional, hospital capacity, civic and institutional support capacity, where depleted. Government's were tottering on banruptcy and malnourishment was rife across war-ravaged continent. So to the general circumstances that prevailed in 1918 were not every remotely similar to what they are today.

Secondly, the mortality rate of the Spanish flu' was a lot higher than Covid.

Many sero-prevalence studies are pointing to infection mortality rates for Covid of 0.25%.

So for your 200m death toll to become a reality would require 80 billion people to somehow become infected!
That's 10 times the current population of the planet.

(Heck, even if the mortality rate was 1% - and we increasingly know it isn't nearly that high - that still means 20 billion people getting infected.)
