Mostly Harmless
Isn't the main advantage the reduction of nuisance lawsuits because the plaintiff has to file in another state so there is a barrier to suing? (assumes both legal systems, tax, etc. are similar)
The advantage to being spread across multiple jurisdictions is that you cannot be as easily targeted with legislation, legal action, tax action, economic action, etc.
Many financial strategies include a foundation of holding a domicile in one jurisdiction, establishing incorporation/trust in another, and holding money in a third. This protects the entity (personal or corporate) by complicating the legal process for anyone wanting to exercise control over them.
