Broadly, there are tradeoffs, including organizational risk tolerance, and which margins one is permitted or not permitted to take which risks on. For example, some software companies are regulated in some jurisdictions. A not-too-hypothetical regulation is "regulatee understands and enthusiastically consents to unannounced site inspections by regulator at any time of our choosing." Thankfully, this doesn't apply to most software companies, but ones who it does apply to have hopefully long-since had a chat with their competent legal professionals about precisely what the definition of a "site" is. There are many, many issues like this, and they're fractally complicated. Even the basics of "How do I hire a full-time white collar employee with the standard package plus equity?" vary substantially between jurisdictions. Setting up the infrastructure for it in a jurisdiction can take the better part of a year. (It would be an excellent thing, for everyone, if jurisdictions decided to compete on ease to employ their residents.)
