When given the coin can be restricted in its use. This means that if you give your kids an allowance in ATD you can dictate what goods this can be spent on. You can prevent them spending this money on things you don't want them to spend it on. Something similar can be done by governments with benefits to the unemployed. For example recipients could only buy food with the tokens. Depending on your politics this becomes "what a great idea" or "OMG this is horrendous". Regardless of whether you think this is good or bad some governments will love the idea and use it.
