Curiosity of EOS Token Sales (ICO)

The following is what has stated in "EOS Token Purchase Agreement". (https://eos.io/purchaseagreement/EOS%20Token%20Purchase%20Agreement%20-%20June%2022,%202017.pdf)

EOS TOKENS HAVE NO RIGHTS, USES OR ATTRIBUTES. The EOS Tokens do not have any rights, uses, purpose, attributes, functionalities or features, express or implied, including, without limitation, any uses, purpose, attributes, functionalities or features on the EOS Platform. Company does not guarantee and is not representing in any way to Buyer that the EOS Tokens have any rights, uses, purpose, attributes, functionalities or features.

NOT A PURCHASE OF EOS PLATFORM TOKENS. EOS Tokens purchased under this Agreement are not tokens on the EOS Platform. Buyer acknowledges, understands and agrees that Buyer should not expect and there is no guarantee or representation made by Company that Buyer will receive any other product, service, rights, attributes, functionalities, features or assets of any kind whatsoever, including, without limitation, any cryptographic tokens or digital assets now or in the future whether through receipt, exchange, conversion, redemption or otherwise.

I am curious if we are buying tokens having no uses and no purposes.

It would be very much appreciated if someone can explain what we are buying from the EOS ICO. Thank you :)
