Running your own node is definitely a friction point but with lightning the bigger friction point seems to be liquidity management, particularly inbound liquidity.
Many of the people using ‘non custodial mobile wallets’ such as phoenix still have to trust the company that is running the node and providing them liquidity.
The concern I have is that we are onboarding a ton of people via custodial wallets and standardizing LNURL which has incentives pushing people toward custodial wallets.
Eventually these custodians will rug pull or shotgun kyc. It is difficult to reverse this course after the fact.
