The czech republic, in general, has below average respiratory outcomes due to higher than average levels of smoking and historically high levels of air pollution under communism (they burned brown coal), as well as an older population (1% of the population experiences acute respiratory infections each year). But all of these factors are improving, with cleaner air, declining smoking rates, etc.

In the first position is Peru with ~6000 death/million. After that there are a bunch of countries with ~3000 death/million including Czechia. And then the number goes down.
Czechia has ~11000000 habitants, so 150K/11M is like ~13000 death/million that is the double of the current country with more death/million and like four time bigger than the other countries.
Apart from the fact that I can't fathom how you could say that 1% of an entire country's population is "not a lot", do you have a source for how many people died as "cost of lockdowns"? I see this being regurgitated a lot but I doubt that more people died due to lockdowns/restrictions than from Covid19 itself.
