Why could not you have both ? No one said that you need Securities transactions to be irreversible. STO can bring more liquidity to property assets and simplify dramatically otherwise complex financial operation (title emission, splitting of subsidiaries and so on). I do hate the point that talks about adoption when we are talking of a technology that has less than 5 years of age (Ethereum for that matter). I hear it a lot and I cannot stop myself to think that this is the same kind of reasoning could have been use again Amazon in 1996 (Bookstore are a small business and Internet has no adoption)
