ok guys, lets get back to basics..
imagine we were on the scale of visa 200million transactions a day.
LN locktime tx is 500bytes minimum compared to bitcoins 250bytes minimum..
thats 100GB of tx's just sitting on the mempool because LN wont use blocks, it just uses the mempool (the unconfirmed unmined database of tx's) until the channel is closed
now imagine people using the locktime for 30 days.. and doing 1tx per day on LN (using the mempool)
3terrabytes of LN tx's sat in the mempool.
now imagine the processing power needed to tally up all the balances of the closed channels to be able to produce a final minable tx for the blockchain..
if you think that tx's are only stored locally, ud be wrong. they need to be in the main bitcoin mempool to ensure bitcoins are locked and unspendable on the blockchain whilst people play around making LN transactions within the mempool..
now the problem is not only mempool storage worries for all them locked bitcoins (unconfirmed). but also whats stopping miners purging them. after all miners are already ignoring Tx's without fee's.. so why store 3TB of locked tx's that wont get them a fee because the transactions are all happening for free in the mempool.
and don't get me started on the end resulting tx the blockchain will finally receive.
imagine 5 customers with 1btc are buying coffee (0.01btc) each from starbucks and then starbucks paying 1 employee's whilst starbucks keeps 50% of customers funds for profit.
remember that bitcoin needs to settle all users balances so that the 5 customers are left with 0.99each starbucks has 0.025 and employee has 0.025.

i dont really see it as reducing much bloat. especially at the expense of large mempool requirements for upto a month, miners wont see the advantage. of holding data for a month for just 1 tx fee
re-empt knitpickers.
dont knitpick the numbers, they are just examples.. instead look at the idea as a whole, tell me the advantages using real life scenarios, demonstrations of what LN can do that will revolutionize bitcoin
