Every transaction will eventually need to be processed on the blockchain. You can try to find ways to do things off chain. But you will eventually need to enter those transactions on the chain.
If bitcoin is to become a widely used currency, that means millions and millions of transactions every hour of every day.
And so each and every node on the chain will need to be able to process those millions and millions of transactions every hour. If you think they will one day have decentralized laptops and decentralized home miners, I think you are delusional. Bitcoin is pretty much unsustainable as a widely accepted currency.
