An overwhelming number of options or choices can actually be a source of anxiety, rather than giving you freedom to choose.

Imagine walking into a foreign supermarket, and having 100 different brands of peanut butter, none of which you recognise. If you have a lot of money, all options are available. If money is a factor, your choices are limited and making the choice is actually easier.

I think he's referring to the situation where too many choices make it difficult to choose as if there was no choice. Or something along those lines.
