This is the kind of theft that puts people in prison fast. It will take years to untangle the whole financial mess, but buying a house with company funds right before a bankruptcy is easy to explain to a jury.
Maybe not too fast (or at all) for SBF though. His father is a Stanford Law professor and that doesn't come without some connection to the rest of the legal world-- and so, assuming SBF is likely to have some method of funding, a flavor of defense along these lines could keep him out of jail:
"SBF was simply an idealistic young man who tried to strike out in a new direction in the financial world. But he'd only had a year or two of experience and found himself in a crypto industry filled with scammers and VC forms eager with FOMO failed to provide the guidance or ensure proper governance as would usually be the case. And so business SBF built was very ad hoc on the inside and when things started crashing down SBF made some extremely poor but well intentioned decisions. But now? He's learned his lesson"
And then he gets his probation and a ban from working in the industry for X years. And maybe even a handslap jail sentence.
Based on what's come out so far that has some small chance of still being how he gets off the hook, but it's early days and getting worse by the tweet.
