miners are still free to choose which transactions too include in a block.
no one forces them to put spam transactions in there.

That doesn't effect blockchain. We have faced serious Bitcoin Core syncing problems before. Dust spam attacks shouldn't be that easy. Imagine with 8 MB block size how much spam attack we get.
what do sync issues have to do with block size?
you obviously have no idea what you are talking about...
and well... its easy to calculate how "much spam attack" we can get with 8mb. just imagine how expansive a 1tb drive is today and how long it takes to get filled... really a big problem
