Honestly you won’t be able to build a device with this thing in it for cheaper than alternatives. For home usage it’s about 50-100$. And a good enough PCI card like Quantis will be 3000$ with a bandwidth of 240Mbps.
And that’s not even discussing bandwidth. In most cases bandwidth (number of random bits generated per second) is the limiting factor in usage. You want them to be fast enough that when you need a number you’re not waiting for it.

You underestimate what a truly random number generator would be worth then.

There are easier ways to get the same level of randomness.

Like a webcam aimed at a wall of lava lamps.

Much easier ways. For example lava lamps

The same level as locally truly random? What provides that same level of random?

Proovably secure PRNGs are as secure as TRNGs. All you need is enough entropy and that you can get from plenty of sources.
A single chip you rely on for entropy is a problem as you cant look inside. Therefore you cant trust it fully.
