I don't want to argue that one should overpay for college because there are many paths to success that don't include an expensive private college. That said, YouTube isn't college. If you want to be a school teacher, accountant, lawyer, research scientist, or work in a healthcare profession (just to name a few) you won't get the credentials you need watching YouTube.
The other point I'd make is that I can see why it's tempting to buy a child a house for $100K instead of spending it on college. It would reduce their housing costs to maybe $5-7K/year (taxes, utilities, maintenance). But if they worked at Walmart, their housing costs would still be a fairly large percentage of their take-home pay, even owning the house outright. If that same kid used the $100K to get a marketable degree (easily done with that much), they would end up earning a lot more than a Walmart employee. In a few years they could save up the $100K again to buy a house, but at that point the recurring housing costs would only be a small percentage of their take-home pay. If they waited a little longer to make sure they had a decent kitty saved up as well, it would generate enough income to pay their recurring housing costs. That would leave them with a paid-off house, no need to work, and a skill set/degree they could use to generate decent income in the future if needed.
