Let’s make this clear. Yes, you can create new cards with spirit. You must create the prismatic versions of them (although they cost a greater amount). You can also create older cards with spirit. The changes you are asking for would increase spirit generation, even if just in the short term.
Even then, I cannot agree that it is a good idea to permanently disable a card for a player. I’m afriad it’s something you’re just going to have to accept.
I’m afraid your car analogy does not translate. We’re talking about a digital product that can only be exchanged at a limited rate for a similar item, no real world money could be acquired. If buying a car in real life meant that I could not sell it or any parts of it except for other cars or car parts, then this would be a more appropriate analogy.
And even then, I’d have to return your question right back at you: Would you buy that car? You stated that you understand you can take your money elsewhere, but I’m not certain you truely believe that. A product’s usefulness and value is defined in part at it’s conception and partly by the value you place on it yourself. If you don’t like the product, don’t buy it. If you don’t like the distribution model they’ve lined up, aquire it by any other means available to you. All products fall into these products. The scope is simply different.
