1st party behavior tracking still requires consent. And nearly every business needs third party integrations. I’m still waiting for someone to give me a working example (a real business )
You are confidently incorrect. Consent is not needed if you only track for your own business and do not send the data to other businesses. One of the big GDPR-compliant website analytics tools, matomo, even has a dedicated page on this topic: https://matomo.org/blog/2021/10/matomo-exempt-from-tracking-...
"Matomo has also been approved by the French Data Protection Authority (CNIL) as one of the select few web analytics tools that can be used to collect data without tracking consent."

The level of "tech" for a lot of trade and local businesses is often just a mobile phone and word of mouth, no online advertising industrial complex necessary. Those are still very real businesses. When advertising is used it's likely "old school" advertising with no tracking or analytics.
Ironically, if you are looking for a tradesman and do stumble upon an online ad or very polished web presence, be wary as it's basically guaranteed to lead to a boiler room full of scammers who will overcharge you and farm out the actual work to the lowest bidder.
