For example, i pay 10 cents to have my trash removed, or 10 cents every time when i flush the toilet. ... Labor based tax ( the one people want to hide form their gov) is obsolete. with utility-based tax, governments are reduced back to what they should do: provide services for citizens.
I don't think so. Our most expensive life purchases are real estate and vehicles. We can't hide either one. If people use cryptocurrency to hide their income sources, then governments will just tax us more on what they
can see. They'll simply assume you're making a certain salary if you own a certain type of property and drive a certain type of car.
If you don't pay up, they just seize your house and car.
In addition, they'll increase the sales tax on physical goods. And if you have a physical store selling physical goods, you won't be able to hide your activity there.
(Of course, you can take advantage of this system if you're wealthy by living your whole life in a low-end house driving a low-end car and not consuming physical goods. Then, congratulations, you die a winner tax-wise.)
