I don’t get it

I read online about Bitcoins security budget issue and I haven’t been able to figure out why it’s wrong yet. Basically, it said that with each bitcoin halving event, the bitcoin miners have less of an incentive to verify transactions. Honestly, the argument makes a lot of sense, but no one has been able to explain why this is wrong. I’m hoping someone on here could educate me and help make it make sense.
