There is no tragedy of the commons here, its the opposite, people create value on previously worthless dns-land. There is no shortage of TLDs, instead an infinite supply, so its not a zero sum game. Of course demand and supply applies

Housing and spectrum are inherently limited so it makes sense to have ‘homesteading’ rules, especially when they are not even rented out

There really isn't an infinite supply though. There are desirable properties of a domain, including memorability (length of domain, typability, common words).

Sure, something like "eebe8X.com" is usable, but it's not very desirable.

[buboard]

the supply is infinite by design, but that doesn't mean that all supply is equal
