I do not think that it is against bitcoin as bitcoin falls under the definition of this. Moreover there is no reason to hate this as bitcoin has proved itself and it is the most famous coin in this market. Bitcoin acts like the fiat money but in digital form.
The reason why they might hate this concept is the fact that physical currency would seize to exist. Almost every year when new coins are minted, limited editions of proof sets are minted for collectors of coins and these are never circulated. If Bitcoin takes over, this practice will stop and these collectors will not have an opportunity to buy these "collector" sets.
The price of the previous proof sets will increase, but the practice of printing new sets will stop.

Physical coins are beautiful to look at and some of them contain precious metals. <Silver/Gold etc>
