If the blocks just keep increasing in size to accommodate small fees then there won't by any (or just a tiny) reward for miners once the block-reward runs out. This will make the hashrate go down significantly and make Bitcoin as a blockchain very unsecure and vurnable.

There was a site that ran the calculations. Assuming terabyte sized blocks you would be able to fund multiple $20 million dollar data centers per year. By fund I mean build new ones.
