I agree with most of what you said except the following points:

...Some may practice Theravada as a kind of hobby, but in any way a layman will need to stay on the level of thinking.
...Think till he will not find a way out.
...letting go of material is the first step...
A layman may serve the Sangha well, a layman may stand behind the ancient way but a layman can only think of freedom and liberation.
That is the way given in the Pali Canon
I would like to deal with the last point first. The idea that a layperson can not practice or is incapable of freedom and liberation is supported by the Pali Canon. If so, please provide categorical evidence that this is the case. It is certainly not my understanding.
Also, I would have thought the first step was not 'letting go', but by adopting sila. I'm not sure what you mean by 'letting go', whether you mean renunciation or letting go of mental attachments. But in my way of thinking, both come as a result of adopting sila, and developing some concentration and insight.
