Um. Lets start with taxes. Taxes are levied by a GOVERNMENTAL AUTHORITY. Never by a casino or lottery.(?) Nor does bitcoin have the governmental authority to demand a tax. The only taxes involved in BTC are what your government imposes.
Second. Bitcoin is not a game, it is money. Nothing more or less, just money. You are fee to use it, in fact you can't be stopped from using it. I suppose if you do have "low intelligence" you are more likely to act foolishly and lose your money. But that is not a bitcoin problem. Such a person is likely to lose their money anyway. They'll get swindled in a phone scam or something.
Maybe you were just being metaphorical? In which case we could say that life's challenges are a tax on the stupid.
