You are confusing Segwit with Lightning network. Segwit is just a version that optimizes transactions. It's an extension of an unused opcode from the previous version, allowing previous nodes to view Segwit blocks as compatible, therefore only requiring a "soft-fork." Pro-Segwit people tend to be pro-Lightning, since it is not feasible to validate Visa-scale transactions in such an inefficient, centralized manner. This camp views Bitcoin more as a user-controlled store of value/bank account, still requiring a hierarchy of processors to handle day-to-day transactions.
