Another hypothetical but ( probably very) unlikely scenario: if two people were cahoots and one accuses the other, and the other was willing to go through with the chemical castration, and manage to prove it in court, and then the alleged offender gets exonerated ( be it with prepared evidence or the accuser admitting they mistakenly identified them ), isn’t the UK just doing a bankruptcy speedrun?

Given the stage of capitalism we’re in, I wouldn’t be surprised if a lot of people did this. Or at least attempt it regardless of how stupid it is? People have done riskier, stupider, and more convoluted things for a LOT less. If that happens en masse, actual victims get less attention and sex crimes start getting taken less seriously.
