Taxes in the future
In my story, a vaguely cyberpunky retro-futurastic setting has digital payments (credit-chits+personal communication devices+identity implants etc). Ie, swipe, insert, tap and go.
What i can't figure out why, though, how/why such a society would also accept taxes in kind. (At customs posts, toll-gates, toll-bridges, etc)
This is a relatively generic cyberpunk world (eg. gangs, low-tech physical augmentation, genetic enhancements, massive wealth inequality, pollution, the government is highly corrupt and incompetent etc.)
The primary revenue collection agency is funded by the government, mostly, so it's relatively self-sustaining.
My question
Why would material taxes-in-kind be valued/accepted in a society where cashless is acessible and accepted.
