It’s an ongoing problem for sure, but the simple answer is users maintaining multiple well connected channels. It’s very common on lightning to pay liquidity providers to balance your channels to you. Lightning Labs has a service called loop where you can pay them an onchain transaction and it will make a lightning network payment to your channel for that amount, thus giving you more spend liquidity. Loop is sweet cause it does this in a non custodial way, look into it.
