Pray tell, where am I misinterpretating the facts? It appears that if you don't pay up, you are denied sacraments. Thus, if it's about money - those sacraments must be "for sale". It's quite logical, and seems pretty evident that this is the case.
For a few people, the church tax is millions of euros. For many it is just a few euros or nothing at all (i.e. they did not make enough money to pay taxes, therefore they made no contribution).
If the bishops were saying that the Church required a minimum monetary contribution, I would say that you had a point.
But the bishops are more than willing to accommodate the faithful who have nothing to give. It is an issue of those deliberately refusing to support the Church as a matter of principle, as opposed to some kind of membership fee.
