To me, this seems like engagement clickbait targeting PG to promote an infotainment product (CTO coaching/course):

>there is no cookie banner law

There definitely is. The article explicitly states this:

>you need my consent when you want to track me

"tracking" here means storing data:

>store information in a visitor's browser is only allowed if the user is provided with "clear and comprehensive information", in accordance with the Data Protection Directive, about the purposes of the storage of, or access to, that information; and has given their consent (wikipedia)

The actual directive also explicitly states this

>consent may be given by any appropriate method enabling a freely given specific and informed indication of the user's wishes, including by ticking a box when visiting an Internet website (32002L0058.17)

>"tracking" here means storing data:

Yes, without any consent. For instance logging in a site, doesn't require the warning.
