Gold, Tulip Bulbs, Rai Stones? (Cryptocurrencies)

>In fact, the former president of the DCB has said that bitcoin mania is “worse” than tulip mania: “At least then you got a tulip.”

How can someone in such a high position say this? Are they unaware of the rarity/scarcity of Bitcoin? Are they unaware that you can send BTC over the internet?

I can see if people were skeptical of using altcoins that print infinity money or sending money to people was a solved problem- But that is not whats going on.

Serious question- why is someone in this position so 'stupid'?
