It makes no sense for it to be illegal. Why do you think that it is?
It makes no sense for a country to legislate against people watching TV from other countries. They have no skin in the game. They are not losing anything by people watching TV produced in other countries.

I can tell you why it is illegal - or at least maybe. It's to do with copyright law and the way it works internationally.
Intellectual property rights (copyright, trade marks, broadcasting rights) operate on a territorial basis - ie. country by country. There are some exceptions where you have groups of countries - most notably the European Union where (eg) you can register a European trade mark.
This mean rights are sold and licenced on a country by country basis. This is because of international agreements about copyright and intellectual property law.
So if you write a book, the agent will sell publishing licencing rights separately for the UK, Europe, the USA, China etc. The same is true if you make a film, it would be licenced territory by territory. Broadcasting is also treated in this way.
The BBC will buy a licence to broadcast The Polar Express at Christmas in England & Wales for example. If you illegally access the channel using a VPN in a territory other than England & Wales, you are knowingly receiving the broadcast unlawfully - because you are outside the territory for which it is licenced.
Television programmes are copyright works that the owners have rights in. It is up to them whether and on what terms they want to sell the rights to other territories to show them - but it's their property so they can set the terms of that and how much the foreign licensee should pay them.
The same is true of broadcasting rights which are territorially paid for. The position became worse in the UK post -Brexit.
You are wrong then when you say they are not losing anything because they are - they are losing control of their property and the rights that go with licencing territory by territory.
Copyright infringement is unlawful and a criminal offence in some circumstances.
The question is whether the access is in breach of the terms and conditions of the channel you are accessing.
Here are some links that explain more about this in principle from a UK perspective but similar rules tend to be applied every where becuase of international agreements:
From 1 January 2021, it became an offence to use satellite broadcast decoders, intended for EU audiences, to access programmes in broadcasts from the UK with the intention of avoiding charges for them

whilst using a Virtual Private Network (or VPN) to add extra security to your online data is perfectly legal – it is illegal to use a VPN to unlock content that is specifically not available within your own country.

The Federation Against Copyright Theft, which acts for the Premier League, SKY, and BT Sport, came up with a solution – Section 11 of the Fraud Act 2006, which criminalizes the act of obtaining any kind of service dishonestly.
