Nah you are confused - you are reading the wrong part of the Regulation. Consent definition is covered under Article 4.11:
"'consent' of the data subject means any freely given, specific, informed and unambiguous indication of the data subject's wishes...."
The key part of the sentence is "freely given" - it has been determined by legislators that this means it can not be a condition of access to a service because then there is an imbalance in the relationship given that if the data subject does not give consent they cannot engage in that service, which means when you put this into the wider context data subjects would literally be excluded from digital society if they wanted to maintain their Art.8 fundamental rights because literally 99.9999% of digital services would eventually simply block access to anyone who does not consent.
Under such circumstances it cannot be argued that consent is freely given and as such it was intended specifically during drafting and trialogue that such activities would be unlawful.
This is also not new - the issue of freely given consent goes all the way back to Convention 108 in 1980 and is actually the same level of protection provided for in 95/46/EC (the previous Data Protection Directive) the problem is 95/46/was secondary legislation and therefore implemented in different ways in different member states, GDPR is primary legislation and has no such wriggle room.
The new ePrivacy Regulation goes a step further in Recital 18 which states:
"Consent should not be considered as freely given if it is required to access any service or obtained through repetitive requests. In order to prevent such abusive requests, users should be able to order service providers to remember their choice not to consent and to adhere to technical specifications signaling not to consent, withdrawal of consent, or an objection."
So this also means that for example - if a data subject has denied consent (say through a Do Not Track signal) but a web site keeps showing those cookies banners over and over again - this would also not be considered as freely given consent.
For -most- digital services it is likely that the ePrivacy Regulation will be the relevant Regulation as opposed to GDPR when it comes to consent - GDPR is more likely to apply to services which are non-digital (there will of course be some exceptions).
