"The poor, who are not interested in putting the entirety of their often very low savings into a funky new cryptoasset in order to be able to use a blockchain."

The above is not only an exaggeration but also applies to Ethereum MUCH more than Steem/EOS & company.

This part of the sentence is just silly:
"putting the entirety of their often very low savings into a funky new cryptoasset"

But forget about THEORY... Isn't this very website proof enough that no one needs to buy anything in order to interact with the Steem blockchain? Sure, Steemit helps to onramp users, OK. But once that tiny stake is in the user's wallet, it never needs to be depleted. This onramping process has orders of magnitudes less friction than anything else in the cryptospace right now.

And let's not forget there are LITERAL examples on Steemit of "the poor" from around the world that joined this network and make a living using it.

As much as the theoretical debate is fun, the proof is literally right before our eyes.
