But if I get paid dollars at the start of the year... and the Dollar 'strengthens' for some reason over the next few months and I buy a candy bar...

I don't have to pay capital gains taxes on those Dollars when I spend them.

How are micropayments supposed to propagate on the internet... if every pay-to-post requires capital gains calculations? Micropayments like on Stacker News are a huge value-upgrade to the internet experience it literally replaces advertising.
