I take free to mean "without cost or payment".
I don't have to pay my employer any money to work for him... does that mean
the money he gives me at the end of each month is free.
I will guess that we will have to agree to disagree on what we believe the word free to mean.
So you are saying that money my employers gives me 'is' free then?
Actually I think you know you are wrong and just don't want to admit it.
And you are right when you say, "nothing can be considered free seeing as everything requires time."
But I think a lot of people would find the process of logging on to a website; inputting their btc address;
filling out a captcha thingy; and then pressing a 'send' button to be not much of an imposition, and so
might consider any Bitcoin gained at such a site to be "reasonably" free. You are asking for much more
than that before you give out any btc.
And the idea about transferring the work to someone else doesn't make what you are offering free
either, the way I see it... there is still a cost.
