Yeah, basically... except I think it's less about "making the strawman real" and more like removing resistance so that there can be no more debate over whether the strawman is real or not.
Take industries that produce toxic waste or are susceptible to environmental catastrophes, like oil, for example. Govern them lightly so that they can take advantage of loopholes and loose enforcement, and they will slowly poison the environment forever until it is dead. Try to speak plainly about what's going on there, and your claims can easily be accused of strawman (ex. environmentalist claims regarding Standing Rock were regarded as over-dramatic strawmen). Under these circumstances, toxic businesses are kept from going wild and producing meaningful backlash, and this ends up maintaining a path to a dead environment (Standing Rock produced an oil spill in less than a year, but not severe enough to produce much reaction in people not directly effected). Now imagine Trump manages to completely do away with environmental regulations, and these businesses just totally wreck shit for a while. Everyone personally suffers for a little while. Sees that it's the nature of short-sighted profit motives to throw a party and trash the place if you let them. Universally agrees to take environmental regulation seriously.
I'm not so sure about accelerationism on the environment, honestly. But that's the logic. It's not "make the strawman real". It's "make everyone learn the hard way, in a way that minimizes extent of damage in the long term."
But I'm very sure of accelerationism on the need to re-invent the economy. We're approaching a post-work model of society, but too many people are resisting it. We keep fighting layoffs and inventing bullshit jobs that aren't really justified wastes of anyone's time to prop up a going-obsolete way of life, meanwhile the needs of the labor market keep shrinking and billionaires keep reaping all the benefits of this ongoing change and further entrenching their power. I'm 100% about making as much work as obsolete as possible as fast as possible so that we can stop believing fairy tales and deal with reality NOW. In the process, people will become more free to invest their efforts in other issues like social justice or the environment, without a desperate need for employment taking up all their time. Drawing this issue out only prolongs and intensifies everyone's suffering, and allows billionaires to keep making themselves more powerful.
