This kind of thinking assumes quantitative changes never result in qualitative change. Which is demonstrably false. Obviously there are thresholds where phase transitions happen.
Take saltwatwer and cell. After some threshold of saltiness is passed, the water flow reverses from into the cell to away from the cell. And the cell frikkin dies.
