Currently, the main disadvantages of decentralized systems are low transaction throughput and poor scalability. These problems inhibit the development of decentralized systems.
that is not a problem of decentralisation. that is a problem of a centralised group deciding not to change the code that has put limits in to prevent scaling.
blockchains can scale if you alter the limits imposed
At the moment it is a major problem until the limit to the code is altered. But my fear is that, if it's altered and scalability sets in, what then happen to transaction charges, do you think it would increase or.decrease?
