Really depends on industry.. maybe at FAANG that is normal, elsewhere - no.
I've worked almost 20 years now and haven't done a real 2-weeker vacation in 5 years, and probably won't again for a while. 4 week vacation is practically unheard of, as is sabbatical.
Of course being a small business owner is not really compatible with 2-4 week vacations, BUT.. you are empowered to make that decision. Maybe you just drag your laptop with you and stay reachable / keep things moving along, but from whatever sunny location you've decided to holiday.
Not much different than my last 6 day vacation where I had my laptop & work phone, and checked in on any urgent fires every morning & evening back at the hotel...
