Order Virtual products as guest

Question

In one of the shops I develop, the whole login system is disabled (customers are not able to register or login, and there is no dashboard).

This works perfectly fine for simple, grouped or configurable products, but is a problem for virtual product (since you have to login to buy virtual products).

Since there is a configuration to enable buying downloadable products as guest, I was wondering if such a configuration is present for virtual products?

Answer 1

I eventually copied the configuration of the downloadable product, and applied it to the virtual product:

etc/adminhtml/system.xml:

<section id="catalog">
    <group id="virtual_products" translate="label" type="text" sortOrder="650" showInDefault="1"
           showInWebsite="1" showInStore="1">
        <label>Virtual Product Options</label>
        <field id="disable_guest_checkout" translate="label comment" type="select" sortOrder="100"
               showInDefault="1" showInWebsite="1" showInStore="0" canRestore="1">
            <label>Disable Guest Checkout if Cart Contains Virtual Items</label>
            <source_model>Magento\Config\Model\Config\Source\Yesno</source_model>
        </field>
    </group>
</section>

etc/frontend/events.xml:

<event name="checkout_allow_guest">
    <observer name="virtual_checkout_allow_guest"
              instance="Vendor\Module\Observer\Virtual\IsAllowedGuestCheckoutObserver" />
</event>

Observer/Virtual/IsAllowedGuestCheckoutObserver.php:

            return $this;
        }

        /* @var $quote \Magento\Quote\Model\Quote */
        $quote = $observer->getEvent()->getQuote();

        foreach ($quote->getAllItems() as $item) {
            if (($product = $item->getProduct())
                && $product->getTypeId() == \Magento\Catalog\Model\Product\Type::TYPE_VIRTUAL) {
