There are several reasons why this argument does not work. The most important is that US law says that US citizens must pay taxes, even those who live in other countries. The only way to avoid it is to give up US citizenship. That can only be done outside of the US, and by an adult.
It's therefore impossible for any US citizen to legally avoid paying tax at least once, assuming sufficient income to have to pay tax in the first place.
Do note that this law also applies to foreign born US citizens, who are citizens by blood but who have never even visited the US. For obvious reasons, many of these citizens either don't know about their obligations under US law, or deliberately ignore it.
Of course you can avoid paying tax at least once: on the day of your 18th birthday, weigh the options about leaving, leave, and renounce your citizenship.
Or, don't work until you decide to leave, and then leave.
That it requires very quick timing or unusual planning to end your obligation does not mean that you don't need to pay it when you are obliged to.
Well in that case, there's no reason to pay taxes at all - simply don't every earn enough to pay taxes. But that's an absurd solution. Otherwise you would have said "You do give consent by continuing to live here past the age of maturity and making enough money to be taxed". (I assume that the major issue is income tax, not sales tax.)
In any case, the current cost to renounce your citizenship is $2,350. You might say it's a "fee" and not a "tax". That label is irrelevant in the overarching context of financial obligations imposed upon a person. Otherwise the US should just charge everyone a fee for having US citizenship and forget about the whole "tax" issue.
It's therefore impossible for any US citizen to legally avoid paying tax at least once, assuming sufficient income to have to pay tax in the first place.
