I think that this analogy makes things even worse, because there are so many Lego sets out there and the Steem blockchain is way behind in many aspects. Instant transaction times with no fees and tokenization (SMTs) are actually a standard with other chainOS like Tron.
Steem wants to position itself as the first and best Lego, while in reality, they are behind in development. The only advantage - whether we like it or not - are actually the active userbase of Steemit (or what is left of it) and not the blockchain itself.
Technology-wise the Steem blockchain can only surprise people either new to crypto or coming from a slow and/or expensive "currency-only" crypto like old BTC - for them, Steem will be a revelation, but for experienced people in the blockchain sphere, I really doubt that...
