While not a "chicken little" I am a bit more cautious when it comes to Bitcoin acceptance.
While legally "property" Bitcoin is still somewhat meaningless in terms of being a recognized global currency.
One can own chicken eggs yet that doesn't make eggs (or Bitcoin) any more acceptable as a formal or alternative currency. Naturally, any property which generates capital gains will be made taxable.

Bitcoin is simply a derivative of useless computer processes. Processes which purely exist to produce the derivative - which thankfully have speculative value.

Now Ripple is another matter...
