If you have operations in RIPE and ARIN regions, it is entirely possible for you to obtain addresses from RIPE or ARIN and use them in both locations, or, obtain addresses from both RIPE and ARIN and use them in their respective regions, or mix and match in just about any imaginable way. Thus, IP addresses don't reside in regions, either. They are merely issued somewhat regionally.

The fact remains that a certain percentage of the population robs banks.

Neither is a particularly good thing, IMHO.

And the quebeckers that care use a tunnel to get an address that doesn't
geolocate to quebec.

Which goes to prove my point wrt. bank robbery.

So called experts who remain rather ignorant in their field of "expertise" are a problem across a wide variety of fields. The internet is not unique in this regard and geolocation is just one aspect of this problem on the internet.

Yep... And even if there were a reason, geoblocking is a joke anyway because it is trivially subverted by anyone who cares and more of a problem for people who should have access but their IP doesn't match their actual geography.

But IP geolocation doesn't help in either of these cases. Those wanting to subvert the programming restrictions simply use a tunnel to do so. On the other hand, a customer who lives near the boundary and gets his internet service from the "wrong side" of the boundary has access to the service from the wrong geography and not the correct geography.

And geolocation by IP doesn't actually work to enforce any of these restrictions because tunnels easily circumvent it for those that want to circumvent it. OTOH, it also breaks the process for those who happen to be victims of unfortunate mismatches between topology and geography.

Where the IPTV provider is also the ISP, this isn't really much of a problem, but in that case, geo IP is kind of redundant.

Where the IPTV provider is not the ISP, it gets very strange very quickly.

Yep... Again, see above comments about ignorance and bank robbery.

Why would I want to help them? I'd much rather give my customers the option of where they want to pretend to be. If I were running a provider that crossed such regional boundaries, I'd likely offer a service (for a fee) where a customer could tunnel through whichever region got them access to the content they wanted at any given time.

ROFLMAO... Indeed... That will likely lead to some very interesting lawsuits and consumer complaints about invalid taxation due to inaccuracies in the geolocation database.
