I'm not sure if follow your logic. I'm not saying you are wrong but I disagree. To me, market making is just a euphemism to wash trading or fake volume. As you pointed:
- Margins in the trading of Steem-Engine tokens are way too high
(but hey that's the real market) - This situation can be corrected by market making activity
ahoa, now we create an entity to reduce the spread by making buy/sell orders (making the market or faking the market activity?) Eventually, most likely often, the 'market maker' will be trading with himself, as the real market is what you state above - Market making can be a damn good business
(ofc it can, one who successfully manipulates the market wins big)
The fact that the 'market maker' is taking risks doesn't say much if he's faking volume or making real trades.
To me, 'market-making' as you said it's just a way to manipulate the market. And it's very different from an investor who just buys low and sells high...It's something usual to lure players and make them think there is more activity that really is. Every exchange does it. In fact, more than 80% of all crypto market is made of 'market makers'.
you can see the definition here:

It's very different from someone who is buying low to sell high. That's what we are actually seeing on the Steem Engine tokens. The real demand/offer for the tokens...
You are saying: "let's create a market activity to attract more players" or you are saying: "Invest in SE tokens because they are a good investment to trade or hold" or "Don't stake too much, put some on trading to provide liquidity to the market"...see the difference?
