If mempool fees keep rising we should all consider using more layer 2s.  At some point it may not make sense for an employer to pay a weeks salary on main chain.  If using liquid all txs are confidential.  Lightning has pretty good spending privacy only if you're using your own node.  Coinjoins are a great tool to use when swapping into these layers to give additional privacy.  Of course there's tradeoffs to layer 2s but until main chain becomes more privacy focused, people need to start considering these second layers to help mitigate these privacy concerns
