Unfortunately, you're right. :o(
Thing is, you don't even have to have a whole lot of money to set up multiple accounts. I started doing this when I was still a student, because I got freaked out by how easy it was to skim cards back in the dizzy. (Maybe it still is, but in the EU most cards seem to smart cards these days so you can't just do the swipe skim anymore – at least, I don't think so.)
I had four accounts:
- A: current account, where I would receive whatever little money I'd make on the side every once in a while, and benefits
- B: savings account, where I'd move most money I received in account A; this account had full freedom but pretty much no meaningful interest
- C: second savings account, where I'd actually put savings; some restrictions but better interest
I also had a mixed debit/credit card connected to A – it had terrible limits (something like £250) but it was enough to make purchases throughout the day. At the end of the day, I'd move funds from B to fill the credit back up, thereby never getting any penalties. It's important not to actually use this credit for more than whatever the allotted free time is. (I think I had 30 days free credit, but always paid it back immediately anyway.) A almost never had any money on it, and if I needed to make larger purchases than the credit allowed I'd just transfer it when I needed it. This setup worked well, and I had a couple of scares where my card had to be blocked, but I never lost money. My savings were abysmal (living hand to mouth) and it was the same funds moving around all the time – I just made sure that my exposure on the card was almost always the bank's money. They're pretty quick in settling things when shit hits the fan then.
This setup breaks down if someone manages to hack the bank or you though, since it's all in the same bank. This is why I use multiple banks today.
Obviously mileage varies by country, but my experience with banks in the EU is that once you've got an account, they're more than happy to set up more stuff for you. (Ye olde Wells Fargo trap, I s'pose.)
Most banks like to insist that you use them exclusively, but I've never heeded that advice and so far I've never had a problem with it. If anything, they seem to work (ever so slightly) harder to get all of your business.
