Prices aren't fixed and prices will be adjusted accordingly, so the absolute token value doesn't matter at all. Every host decides the price individually. The buying power of tokens is relative to the total supply of storage. If you hold X% of the tokens, you can buy Y% of the storage supply. This is true now and in the future, which is the mechanism for the increasing value of the Siacoin tokens, because the total network get more valuable as it grows.
