Getting a high market cap is very simple: price per coin * number of coins = market cap. You either have to increase the price per coin or the number of coints or both. We already have the number of coins increasing and there are no plans to change that any time soon that I'm aware of. Price per coin only happens when more people buy the coin than want to sell it. That's all I was saying.
We could discuss various strategies and reasons for why someone would want to buy STEEM. I think you're argument has something to do with there being more of a marketplace to use STEEM as a currency. I like that perspective and hope it to be true, but Ned said something at Steemfest which stuck with me concerning currencies and stable marketplaces. If the price of the currency fluctuates too much, people won't use it to buy things and merchants won't want to sell their products for it either. It may be a chicken and egg problem, but ultimately the replacement of the fiat system with a cryptocurrency system is the number one way to increase the market cap as more people exchange their fiat for cryptocurrency.
And don't even get me started about the Bretton Woods agreement. From my perspective, the United States basically screwed over the world by taking all their gold.
