you entered an agreement with the government when you where born, just as you did to your family.
You're mistaking "government" and "society". This is an error in logic that is causing an accumulation of errors in your other reasoning. One of those errors is the mistaken idea that we entered into a "contract" with a force that has no care for consent or reason.
A little Thomas Paine might set you straight:
Some writers have so confounded society with government, as to leave little or no distinction between them; whereas they are not only different, but have different origins. Society is produced by our wants, and government by our wickedness; the former promotes our happiness positively by uniting our affections, the latter negatively by restraining our vices. The one encourages intercourse, the other creates distinctions. The first is a patron, the last a punisher.
Society in every state is a blessing, but government even in its best state is but a necessary evil in its worst state an intolerable one; for when we suffer, or are exposed to the same miseries by a government, which we might expect in a country without government, our calamities is heightened by reflecting that we furnish the means by which we suffer!
this agreement allows you to take advantage of free education, and other public services, and the government to take taxes.
I'd rather die in the gutter than take one penny from the State for my food, shelter, clothing and education. I make my own way, thanks.
And this you say at a network made by the US department of defence, on a computer only made possible due to public research?
