If you seriously think that Dash can morph itself from a POW to a pure POS asset, ditch mining and "everything will be ok" then you're seriously deluded. That is "maki-it-up-as-you-go-along", "that didn't work so lets try this" type stuff.

Dash only ever had one thing it could out-do its competitors on and that was to support a VERY high mining quota WHILE simultaneously providing services. --- End ---

The services you speak of are not a replacement for mining, they're a compliment. They're not equivalent to the smart-chain business model in any sense for several reasons, amongst them being:

 • Ethereum type services run on-chain and consume blockchain tokens directly. They are more akin to a fiat type monetary system where liquidity creation responds to demand and that demand is derived form on-chain activity

 • Dash services are designed to run off-chain so there's no such "sink". Dash inherits bitcoin's economic model where value is supported by scarcity and primary market demand (a.k.a. mining). What services do for us is augment our competitiveness against other mined assets by being able to match their mining quota but blow them away on useability

However if we simply ditch the mining thinking we don't need it it's a bit like an aeroplane designer ditching the wings so they can carry more passengers. None of our services wil be worth anything if we can't store value and we can't store value without mining. We are a POW coin and that's what POW coins do.
