I know your example was only illustrative, but the straight answer is that if coke was unavailable, that people would buy pepsi. And if not pepsi, then snickers. And if not snickers, then pizza. We'd go down this list, likely making some net gains, but not to the extent that we are measuring.
Nobody chooses what they want because they just want "it". They have some relation to it, which is more complex than mere wanting. That relationship is defined by what the person _needs_. The soda is merely symbolic of taste pleasure, and pleasure is tied with disassociation, and disassociation is tied with pain.
People live unhealthy lives when they are in pain. When we stress them out with the modern environment, and we merely take away one of their crutches, we're merely asking them to seek another drug. And sometimes with drugs, they don't pursue the less dangerous kind next. It gets worse.
Something else to consider about the modern Coke-drinking world: it is a relatively peaceful and safe time, right? According to the numbers at least.
If we're going to ask people to leave their positions of safety and comfort to come hunt with us, we need to inspire them. We need a narrative for why the Coke is bad and why someone becomes a fundamentally better person for not drinking it. It's the same think NoFappers do with their material, whether you agree or disagree with it.
