Leaving aside that you are completely delusional about the role of government, you are also delusional about the goals of professional lobbyists. Lobbyists are not "spying" on government, they are attempting to use any means, fair or foul, legal or illegal, to sway legislators to promote the special interests they represent, and only the special interests which they represent. They don't represent any kind of democratic institution, because they are predicated on swaying legislators without reference to the wishes of any particular legislator's constituency.
Democracy, in this republic, finds its expression in the citizens threatening holders of public office with loss
of their jobs at election time. In order to do that, the citizens need spies
to watch the politicians at federal, state n local levels of government,
in legislative & executive roles. The citizens r too busy
to do the spying themselves and then to analyse the information
that thay glean insofar as it affects that special interest, be it
small business, labor unions, the Sierra Club, the NRA, the AMA,
the National Association of Mfgrs., the NEA, PBA, NAACP ad infinitum
their members (voters
) about what the politicians r doing.
That is the reason that Congress tried to SHUT THEM UP
B4 elections, until its too late.
Most pointedly, that was how Hillary 's health care package was killed,
during the Clinton Administration, freaking out n frustrating
The voters sent Congress tons of negative mail.
Democracy squashed liberalism
