Great article, I really enjoyed reading it, so much so that I followed you. I can tell you are newer to steemit because for a long time steem was well above $1 and like you say in this article it helps a lot more people at that price.. However, I personally don't think we don't need a single big investor to come and scoop up so many coins, because that would just make more whales or people who have more control over something that is supposed to be decentralized.
What I believe we need many people to buy small amounts of Steem because they are transacting regularly, using the blockchain and want to swap money for cryptos for bigger upvotes, for DApps like 
In any case when cryptos really start to taking off again $1 Steem will be easy. Then when that happens we will get a lot of people to invest quick so the price will go well beyond that because everyone has FOMO. I have seen it multiple times before on this platform and you will be surprised how fast the price of Steem will rise. The real problem is keeping it there.
Since Steemit Inc doesn't have a revenue source they are constantly selling steem to pay for everything and it's a lot of steem! That puts constant downward pressure on the price of steem which ultimately causes it to collapse when moral is low in the cryptoverse. What we really need is to make steemit profitable through adds or some other revenue source so that constant selling from steemit inc can stop or atleast dramatically slow.
Last but not least, we need to get more advertisement about Steem/Steemit&Cryptos in general to the masses and make them more user friendly so people are inclined to join and continue using steemit and all its great DApps all while getting payed to do so!
Sorry about the long reply, just my two cents worth ;) Take care friend.
