Maybe a stupid question, but wouldn't a block size of 100 MB 200 or even 300MB fix a lot of issues with the speed, transaction fees and so on? This is not taking in consideration?

Many people already discuss about this and it's concluded it's not good solution since it could risk decentralization since huge block size means only people with very fast internet connection, computing power who can run full nodes and storage capacity if there are lots of transaction. One of possible scenario are government/group control majority of bitcoin nodes and mining where they can prevent transaction from get confirmed.
