In the 3D-Designer examples above, could you define what taxes everyone involved is paying? I rather sure that no person has every paid taxes for the production of their own CV, unless they create a sole proprietorship, in which case its very likely that they are doing something commercial.
> what other types of compensation makes it commercial/non-commercial
The Swedish tax office define income as work done under compensation. Gifts, in contrast, is valuables given with no expectation of compensation. Income is taxed, gifts are not. In your list, YouTube clicks, Facebook likes, attention and awareness is not taxed as income. Bitcoins were not taxes either when they had no value, but are now when given as form of compensation.
