"This makes it easy for people to enter the world of cryptocurrencies and accessible to people from all walks of life" ....true, e.g  myself. 
"...opportunity for anyone who can use the internet to earn value through their online interactions, their creative and cognitive efforts, and to be the captains of their own financial ships."...thats one of the best things about steemit. 
As regards to it being undervalued, you have said it all but I believe it's just timing i must say but with its value shifting at its current rate, Sooner than expected the value of steem will climb higher than predictions.
