Very good post.
However, I would like to point out that the price on Bitcoin is not simply the brand. The Bitcoin brand is valued as much for a very unique quality that only bitcoin has in this space:
Governance.
While most other currencies are in their infancy and they change their code base basically at will... they rebrand, they even freeze or fork themselves. That isn't the case in bitcoin for the past years.
For a change to take place in bitcoin, the community needs to signal for it with more 90% of hash power, and nodes have to agree, etc, etc... Even the huge bitcoin2X propaganda move was not able to turn the tables on the "unruled" bitcoin. And that has a lot of value.
To make sure that the main property we are striving for, censorship resistant, is indeed maintained in the long run, there is no coin other than Bitcoin that has already shown a huge resistance to changes.
Being a "fast system" is only temporary, until they can proof that is not the case when they get bitcoin level transactions.
(IOTA basically failed at that, for example, and they had to "restart" their system a couple times with snapshots)
