I'm happy we've done away with hyperinflation, but that's no reason to remove SBD since it wasn't the only way of escaping the hyperinflation to begin with. In fact, there were many options to avoid the hyperinflation of STEEM (including SP, almost any other cryptocurrency, most fiat currencies, etc.)

For many people, the primary value proposition of SBD was (and still is) instead to escape the volatility of cryptocurrencies, while still holding an asset 100% in their control (i.e. zero counter-party risk). In fact, I would argue that this is the best reason for most people to hold SBD (perhaps aside from earning interest, depending on your needs and point of view).

Some have also argued that SBD causes systemic risk. But in that case why not just lower the interest rate (substantially, if need be)? That way fewer people will hold it, but it will remain a selling point for some % of people that otherwise might not consider the platform.
