You completely miss the purpose of government. I can hardly do better than to quote the US Constitution:
"We the People of the United States, in Order to form a more perfect Union, establish Justice, insure domestic Tranquility, provide for the common defence, promote the general Welfare, and secure the Blessings of Liberty to ourselves and our Posterity, do ordain and establish this Constitution for the United States of America."
However if you insists on government as a service provider we have off the top of my head:
defense from enemies both domestic and foreign, infrastructure (roads, dams, water, airports), courts for business disputes (patents, labor issues, contract enforcement), technology research and development (note the internet was created by the government agency DARPA), libraries and universities supplying educated STEM employees as well as free primary schooling for their children.
