Do you have any evidence of that? I think the OPs are assuming this as a premise so their logic is probably valid but may not be sound logic for you.
Instinctively, if we suppose all the newbies freelancers without any reputation start with the same lowest rate possible to be competitive, passing additional cost to my client will mechanically increase my rate. Putting me in disadvantage about getting any work. And with the difference of monetary value for the same price of tokens, the rate delta is higher.
It's a simplified model of the world, but it feels like simple economic rules.
I assume the comment I'm referring to was written by someone who is already established and for Wich the token cost passing is lower relatively to my environment.
