Guys, sorry that I haven't gotten a chance to get back to this thread until now.
No, you can't buy VIP tickets for coins.
Yes, you can use coins to pay for parcels and buildings and pay your maintenance on those buildings. Allowing this does set a "floor value" for these coins. There is, however, is no "ceiling" for the value of these coins. You can't buy coins directly from us, so the value of these coins will still be determined by negotiation between buyers and sellers, somewhere at or above that floor value.
You also can't freely exchange between parcels and coins and VIP tickets, which means you can't arbitrage. You COULD be a property broker (trying to "play the market" between coins, buildings and parcels) but I'm not convinced that is a bad thing. It actually sounds pretty fun.
Also: none of the above things were changed or affected by our decision to include Coins in the design.
In the previous iteration of the design, you had to spend a set amount of wood/stone/ore to purchase parcels and buildings. That meant that wood/ore/stone were effectively units of currency, and these currencies had a "floor" value. You could also trade these for VIP tickets, so that loop already existed, too.
Coins just gives you an easier way to facilitate these exchanges. In addition to the benefits to the players (easier transport, providing a common language for "value" and, most notably, being able to set a price for an item on a vendor so that the NPC vendor can sell the item to someone else while you are offline) it also gave us a common currency to collect maintenance/taxes on buildings. Which, again, is nothing new (otherwise "tax free parcels" wouldn't be particularly valuable) it's just making it easier on the player.
If we hadn't gone this route, the alternative was to inclue a "value" attribute on each item, so that you could know how many chickens to place in your building to pay maintenance on it. Effectively, this would mean a "gold value" on each item. If we had gone that route, we still would have had the floor (because we already did), we would have still have had the loop (because we already did), players would use the same value calculations when making transactions (because of course you would), only it would be harder to make transactions (because it's hard to give someone back 10 gold in change when they paid you with a chicken.)
This isn't really that big of a change. Coins are still inventory items, they are just a more stackable version of ore. You still need materials to upgrade your buildings. You still need materials to craft goods. And you can still trade rare items and materials for whatever you like; you don't HAVE to sell them to anyone for coins if you don't want to.
