Depends.

I got $300,000 in coverage for a catastrophic event and wound up paying $ 3,100.

But I did have good insurance with United Healthcare.

Quick numbers that I found suggest lifetime healthcare costs of >$300k even if you're 65 already (with current yearly spending trending more towards $600k-ish).

So even with a (single) catastrophic event just paying yourself might save you money still (which seems insane to me).
