I'm for increase of block size, even if I believe Bitcoin to be a store of value that you won't use so often to transact directly.
But ~5 transactions per second is not enough.
We mustn't try to include worldwide transactions in the blockchain, but 5 ts seams really to low for me, and as it was explained before, if we don't do this, we will loose ability to transact directly.
The worst part of it all is that the current limit doesn't even support 5 TPS. According to D&T it is even lower.

Yet 1 more time:
Increasing the block size limit by a factor of 20 does not increase the size of the blockchain by the same factor! The chain will grow gradually over time.
