The problem source is that the "cost" of tokens are taken at face value from business that are losing money at record speeds. E.g. https://artificialanalysis.ai says "doing task A costed us $10 using OpenAI", and that is the "cost" the OP used as basis for "tokens are cheap". Meanwhile OpenAI is losing $19 for each $1 in revenue... So right now OpenAI should be charging around $200 to do task A just to break even, but that would mean their use base would collapse.
There are two different things occurring here.
One is how much does it cost OpenAI to train the model.
The other is, if I stole OpenAI's model how much would it cost for me to run it?
R&D costs versus operational costs. Operational costs are very likely profitable. R&D is catastrophically expensive currently.
