What is the word which describes the absence of formless, of long procedure with bureaucrats? I was thinking about formsless but it sounds weird...
How about streamlined:
streamline, v.: to improve a business, organization, process, etc. by making it more modern or simple
Freedonia streamlined its archaic visa application bureaucracy, replacing it with a three-question online form.
There isn't a single antonym for "bureaucratic", because "bureaucratic" encompasses a number of ideas, although I think streamlined or possibly efficient is perhaps the closest to what you want in your case.
Other examples that you might want, depending on what aspect of the word "bureaucratic" you are contrasting include:
easy, simple, transparent, efficient, flexible, fast, direct, bespoke, personalized, streamlined, ill-defined, unprepared, undefined, undocumented, unaccountable and elected.
Absence of red tape or cutting the red tape could be used:
"excessive bureaucratic rigmarole," 1736, in reference to the red tape formerly used in Great Britain (and the American colonies) for binding up legal and other official documents, mentioned from 1690s.
Red tape is commonly accepted to be a barrier to business, particularly small business. In Canada, the Canadian Federation of Independent Business has done extensive research into the impact of red tape on small businesses.
The European Commission has a competition that offers an award for the "Best Idea for Red Tape Reduction". The competition is "aimed at identifying innovative suggestions for reducing unnecessary bureaucracy stemming from European law". In 2008, the European Commission held a conference entitled 'Cutting Red Tape for Europe'. The goal of the conference was "reducing red tape and overbearing bureaucracy," in order to help "business people and entrepreneurs improve competitiveness".
Non-bureaucratic seems to me to be the obvious term to describe the absence of bureaucracy, but it may not be appropriate in all contexts depending exactly how you intend to use it.
a philosophy or practice characterized by a usually deliberate abstention from direction or interference especially with individual freedom of choice and action
Yeah, I believe 'freedom' is the best answer to your question.
1 : the quality or state of being free: such as
a : the absence of necessity, coercion, or constraint in choice or action
b : liberation from slavery or restraint or from the power of another : INDEPENDENCE
c : the quality or state of being exempt or released usually from something onerous, freedom from care
Adhocracy, or in a positive business context, bureau-adhocracy.
