The government's responsibility is to ensure that our rights are not limited.
Your antic definition of government necessarily negates government.
Universal self-indulgence is hardly the hallmark of any advanced society.
What?
The Constitution is written to negate universal self-indulgence.
The process to amend the Constitution is deliberately difficult. Fads, whims, and Marxist/Socialist/Communist mentalities are flash in the pan concepts that are harmful and the Founding Fathers set forth to make it exceedingly hard for these kinds of 'societal' changes to happen.
Slow and deliberate is the correct path.
History shows us that governments are harmful and universally corrupt. That is why individual rights are supreme and exceed the power of government. This was the intentional condition of our country.
