...Nobody will make me pay taxes from tokens that are lying on some address without my name on it and that I can't spend on anything in my country but have to use an exchange first. ...
It is possible that it will not always be this way. You have to keep
in mind that the whole industry is still in its infancy and regulators
are still playing catch-up to keep up with the latest developments
in the cryptocurrency scene.
Nowadays, most ICOs require you to complete a KYC procedure. If you buy
tokens in an ICO where you are KYC verified it is entirely possible that one
day the tax agency of your country will come after the people, who participated
in the token sale and didn´t pay their taxes.
