To what extend the system is unhelpful here? Might be that I'm missing something being a frequent public transport user and being active in a regional public transport interest group, but always happy to help.
As an example, I recently used the local transport systems in Prague, Munich and Amsterdam.
In Prague I bought a day ticket for everyone, made sure it was stamped on first use then all I had to do was carry it around and make sure to get new ones after 24 hours.
Munich would have been similar (with a bit more attention to what zones I needed) if it wasn't for the 9 Euro tickets currently available.
In Amsterdam you have to tap your day ticket every time you get on and off a bus or tram even though you've paid for 24 hours unlimited travel. I don't know if it really stops working if you forget to tap off (I dson't know why it should) but that's what the rules say and I was firmly told to do so by the conductor on the tram who sold them. It's not very convenient, especially when you're travelling in a group and have to make sure everyone does it properly.
In Prague and Munich everything was integrated so one day ticket covered all forms of transport including local trains even though they had a different operator to trams and buses etc.
So far as I can see in the Netherlands you have two options for local travel - tickets valid for a certain period (say 2 hours or 24 hours) but only on one operator (and rather expensive for a short single journey), or get an OV chipkaart. As I understand it an anonyumous chipkaart is 7.50 Euro per person to buy, and then there's the hassle of making sure that everyone's card is sufficiently topped up. I don't know if you can get the left over balance back at the end but if you can it's still more hassle.
Going back a few years, the Netherlands were unusual in my experience in that NS ticket machines (apart from Schiphol) wouldn't take credit cards but I think they did take some kind of debit card widely used in the Netherlands and not available to visitors.
It surprises me that such a small country seems not to cater particularly well for foreigners. (I also find it interesting that the NS journey planner won't do international journeys - it sends you to a separate web site unlike the Czech or Germain planners).
I wouldn't say that the UK system is particularly friendly towards foreign visitors either, but we are a bit more isolated as a country so it's perhaps more understandable.
