In the real world you don't spend a lot of money at once so 99.9% of the people won't ever see this problem (it exists for fiat too, and no one cares that you can't withdraw 100k)
And LN will end up being centralized so you'll just have to up all your money to a good hub (aka bank) to have no liquidity problem
And I believe the population will prefer to use that kind of system so that no one can see what they buy (this isnt true for bch, you need to shuffle and care of what coin you spend)
