People are trying to force Bitcoin to become mainstream, before it is ready for mainstream use. We saw what happened before SegWit was around, people spammed the Blockchain and the result was high fees, due to congestion. The developers was already two steps ahead and they provided us with SegWit.
SegWit took some time to find it's place and now tx's are much cheaper due to it's implementation and spamming the network became more costly and that stopped the "spammers" for now.
As I said, the developers were 2 steps ahead and they worked on the latest scaling solution called the Lightning Network and the adoption and testing is now being done for that.
Just give it time, scaling is already not an issue anymore.
