Now, when Steam decides that you have violated their ToS in some way, they will close your account and lock you out of everything you bought. This happens, rarely, but happens. Do you want to be dependant on an idea of a corporation that they will treat you fair? Are you OK to give away your washing machine and oven just because you had troubles with finances and you missed one payment?
We're more dependent on corporations when we buy things, since we have given them all the money upfront. A service model gives us more leverage. As someone who had to throw away a washing machine because the company wouldn't service it, I would have very much preferred a rental model where the loss would have been theirs. To flip your question: Are you okay not being able to buy a washing machine because you couldn't…
No, we aren't and no, it doesn't. Buying things up-front means your interaction with a corporation is brief and to the point. With service model, they get to gouge you for money and restrict the things you can do with the item you now don't own, but rent.
> Are you okay not being able to buy a washing machine because you couldn't make a significant one-time payment?
There are plenty of ways to amortize that using third parties that have no interest in limiting your control over the washing machine.
Also, it's you who get to choose when to do the purchase. Once you enter a contract, you'd better have a stable paycheck for the entire duration of it, or you'll be SOL.
