The biggest risk with starbeam.one -- as is the case with any business -- is that the efforts here could fail and it goes out of business. When digital ownership is involved, this is a double-whammy, as all those assets are theoretically nullified. This is an identified risk and one I obsess over.
While I am fortunate enough to be the first centralized digital ownership offering to market, I do not expect to be the last. As such, my feeling is that every centralized digital ownership solution should offer a "living will" of sorts to inform its users what they can expect if the worst happens and a profitable business can not be achieved and/or maintained.
