Because as I recall a lot of computers are still sold with 32-bit cause it's cheap software.
A lot of computers meant for casual users are sold with 32-bit versions of Windows preinstalled and/or a 32-bit install disc bundled, yes. Largely because their initial configurations are quite limited and the users are not expected to upgrade them beyond those.
However, to the best of my knowledge, the license keys for Windows 7 and up (I am not sure about Vista) work for both 32-bit and 64-bit install media: all you'd have to do is get a copy of the 64-bit setup disc (which I seem to recall hearing can be downloaded from Microsoft's website) for your Windows version, backup your data, install the 64-bit version and enter your current license key.

While it is unfortunate if someone is stuck on a 32 bit machine and is not in the financial situation to upgrade, you don't need to replace the whole system. You can keep your case, GPU, PSU, and depending on whatever motherboard you get, your RAM. All you would need to replace is the CPU and the MOBO.
Pretty much any machine new enough to run MWO will have a 64-bit CPU.
It's just a matter of installing a 64-bit version of Windows.
